Wakeboarding Essay example - 592 Words

Wakeboarding Wakeboarding is a fun and challenging sport. A couple of years ago I was boating with some friends when one of them pulled out something I had never seen before, a wakeboard. In the past I had tried water-skiing and kneeboarding, but until then I had never heard of wakeboarding, I havent picked up a water- ski or kneeboard since that day. A wakeboard is shaped a lot like a snowboard. It is 150 cm long and about 60 cm wide. Riding a wakeboard has been compared to surfing, skateboarding, waterskiing, and snowboarding. At first I was nervous about learning a new watersport at age 18, because I remembered how hard it was to get up one ski. My friends convinced me to give it a try and I loved it. At†¦show more content†¦When I first started going fakie it was like learning to wakeboard all over again. Just recently I have gotten to the point where I can ride regular or goofy in any water conditions, choppy or smooth as glass, and feel like I am doing well. Just recently I wa s able to land a jump that I started in the regular position executed a 180 degree turn and landed in the goofy stance. This took me hours and hours of practice, but overcoming the challenge was so exhilarating that it was worth the time and effort, and made me even more excited about the sport. The next skill I have been working to acquire is grabs. A grab is contorting your body into different positions then grabbing the board with one of your hands while jumping. The most complicated grab that I can currently land is starting the jump in the regular stance, while in the air I reach through my legs grab the back of my board and execute a 180 degree turn landing in the goofy position. Im excited about continuing to improve and learning to tweak big air in this new and exciting sport. I am working towards a goal of being able to land a backflip within the next year. Currently I am really good at landing on my head. But for some reason when I am wakeboarding even landing on my head d oesnt hurt.

Aboriginal Education strategies

Question : Discuss how the following Aboriginal Education strategies are reflected in the Early Years Learning Framework (EYLF) in NSW and Australia and their importance to the early childhood sector. Answer : Introduction The whole world perceives Aboriginal education strategies as a crucial key and an optimistic endeavor towards the development of Early Childhood Education and Care (ECEC). It is a positive step by the Australian Government to encourage the early childhood educationalists in the format of EYLF or Early Years Learning Framework. The first document that was published with a strong objective of intensifying the early education of children up under the age group of five years and also their learning all the way through their move into school. That is why the Melbourne Declaration on Educational Goals for Young Australians also intended for the children around Australia to get the knowledge about the significance of indigenous cultures and what are the needs as well as benefits there regarding this study. The ultimate goal is to enhance and widen the understandings between indigenous Australian people and non-indigenous Australian people. In point of fact, this reconciliation strengthens t he base of the prospective education system of Australia and especially in New South Wales (NSW). The maximization of the moments of fortune and the opportunities for promising and budding children is the vision of the COAG (Council of Australian Governments). A superior future for every child and for every country is a dream that can be achieved by a supreme initiation in the life- It is the idea behind this commendable framework. The period of early childhood put a huge effect in the life of a human being as it is the most fundamental age in which a child gets to know about diverse things. This period is very important as the ultimate education, wisdom, intelligence as well as development of a child depends on this particular time. NSW as well as Australian Governments put substantial thoughts to the early days of children along with their early childhood education. Qualitative learning techniques together with immense experience in children care is the primary elements of this fr amework. There are different education programs regarding early childhood for which proficient educators are appointed, whose utmost emphasis is on play-based education, literacy along with numeracy in early periods with their importance, communication skills, language knowledge, social development within a culturally safe environment etc. These educators of early childhood learning work with the families of the children and the proposed framework was designed in this particular manner. The convention of United Nations on the Rights of the Child explains the support of early childhood educators on a daily basis and it is directed by the Early Years Learning Framework. According to this framework, each child has the right to take advantage of this education policy and thereby exploit the skill as well as esteems the culture, language and family. The relationship of this framework among all the states along with the territories is established according to the jurisdiction by each of them. The additional goal of this framework that was put together by the Melbourne Declaration on Education Goals is based on the development of Young people in Australian. The improvements of Aboriginal along with young persons of Torres Strait Island is also entrusted with this early education plans. Filling up the persistent gap between the indigenous and non-indigenous people by strengthening the early education system is the one and only motive of The Council of Australian Governments. Cultural security is one of the essential issues related to the children of Aboriginal as well as Torres Strait Islander which is conducted with special perception through this framework by the educators skilled with added guidance. For additional supports, all types of resources are made available to the educators for the development of early youth education t hat comes under this imperative framework. The prime vision of this remarkable educational structure is to create effective beginners for world-class academies, build the minds of the youngsters in a positive and ingenious manner and with all these they become actively participate in the progress of Australia in the form of an educated and conversant citizen. The strategies regarding Aboriginal Education are the crucial elements in the EYLF (Early Years Learning Framework) in NSW and Australia. These strategies mainly involve Aboriginal point of view in the national curriculum, their methodologies and approaches: In 2010, The Australian Curriculum and Assessment Reporting Authority, known as ACRA conceded the fact of reconciliation between indigenous and Non-indigenous people. Here the standpoint was to bring together them for which looking towards its importance the national curriculum is being written in the viewpoint of Indigenous of Australia. According to it, all the teachers in Australia have to set in the Aboriginal perspectives in all the educational sectors. The three Elements related to the framework: There are three major elements which are inter-related in nature are like the building blocks of this whole educational structure. These core elements all together constitute the framework and very important in the development of early childhood education. For childhood pedagogy, these elements play a very fundamental role. These vital constituents are- Code or Standards of this education policy Its importance and the practice The outcomes Decision making abilities along with the pedagogy also comes within the curriculum. The knowledge of children towards the world is shaped in this program of study. So, anything the educators include in this study as well as exclude both the aspects affect the learning and development process of the children either in a positive manner or in a negative manner. It is the reason for which the educators are guided in a proper manner. Children are very open to new ideas and that is why all the interactions, doings, events etc. are new experience for them. So, intentional education is more emphasized because it can be conducted in a well-planned manner. Relationship building along with decision making abilities is also given more importance in the childhood pedagogy. The strategy also includes the betterment of relationship among the educators, the children as well as the families, as it affects the learning process very much. Play-based education is considered holistic because it covers all the factors like- physical as well as emotional nature, personality, creativity, language dexterities and many more. It originates and strengthens the concepts of relationship within the minds of children and of course it is like a fuel of happiness that is edified with wisdom to the children. Apart from all these, each child is gifted with a unique ability; the educators are guided to recognize it. It is an intentional study by which one day the child will be known for its uniqueness. The framework is not only for the educators but also the inputs of the families as the practices of the educators together with the connection of families and children put significant positive effects in the learning and development approach. Children learn many things from thi s relationship. Positive attitude towards the education in case of both family and the educators is really important. In addition to it, the outcomes play a key part in this early day education (Goodfellow, 2009). Effects of the framework for Aboriginal children: From the period of a new born baby to the age of five, this educational policy has shown its significance for the wellbeing of a child. There are several outcomes which are certainly evident in nature and found in most of the cases. Powerful sense of distinctiveness and identity can be perceived in case of children. Children are generally very good in communication and it is god-gifted. Children have excellent confidence and superior learning skills. Wellbeing nature of children with an active sense towards happiness is also an outcome from the strategy. Children have a strong feeling of getting connected with their world. These outcomes are very often influenced, especially by the capabilities of the child at present, families and societies, environment around the child, the different practices, activities and routines of the educator etc. It is because; children hold complex thoughts throughout the learning as well as development processes as these are new experience for them. The constant nature of childhood learning affect the child and in due course the child steps forward to the outcomes (Harrison, Goldfeld, Metcalfe Moore, 2012). Conception of a culturally secured environment for learning and development of a child: Cultural proficiencies enhance the abilities of a child to get knowledgeable about diversity of cultures. It is thoughtful intention stated in the EYLF. Secure relationships along with equity in partnership come from this idea. In the ongoing education part, the educator has to teach this and one of the principles of the framework encompasses it. Cultural identities of children help to know about themselves properly. Positive feelings are reflected from the competency of cultural differences and it is very essential for a child. A concept of wider and extensive community can be put in the minds of children with the help of cultural experiences by the educationalists. Differences about race, traditions, way of life, civilizations, societies, backgrounds, customs etc are very important factors that help the child to understand the outer world. To fill the gap, EYLF came with an idea of learning outcomes in a modern approach with cultural ways. Equity can be better taught to the childre n and they can know more and more about the environment of their own neighborhoods. Apart from these, perceptive knowledge about the indigenous culture and the people are some of the key points regarding the culturally safe environment relate to this remarkable educational framework (Anning Edwards, 2006). Conclusion: The early childhood educational period in NSW and Australia is being conducted very effectively. It is because; currently the governments have known the value of this educational policy and its input in the aspiring future and progress of the nation. Worldwide programs have been introduced that are being carried out properly including all the principles, practices and outcomes. The educators play the most important role in the entire framework and thats why supreme quality guidance is the only vision of all the states and countries, because- PROGRESS OF A CHILD IS PARALLEL TO THE PROGRESS OF A NATION.

Electromagnetic radiation and health Essays - Radiobiology Electromagnetic radiation and health The preponderance of evidence does not suggest that the low-power, low-frequency, electromagnetic radiation associated with household current constitutes a short or long term health hazard. Some studies have found statistical correlations between various diseases and living or working near power lines, but no adverse health effects have been substantiated for people not living close to powerlines.[19] There are established biological effects for acute high level exposure to magnetic fields well above 100 ?T. In a residential setting, there is "limited evidence of carcinogenicity in humans and less than sufficient evidence for carcinogenicity in experimental animals", in particular, childhood leukaemia, associated with average exposure to residential power-frequency magnetic field above 0.3 to 0.4 ?T. These levels exceed average residential power-frequency magnetic fields in homes which are about 0.07 ?T in Europe and 0.11 ?T in North America.[20][21] 19.^ Electromagnetic fields and public health, World Health Organization 20.^ "Electromagnetic fields and public health".

Evaluation - Essay Example The movie drew numerous reactions from Americans. For some Americans, the movie exposed what has been happening in the health care system denying the Americans the level of health care they deserve. For others, the movie is, but an exaggeration of the existing drawbacks in the health care system. A close analysis of the movie reveals that Moore addresses critical issues that need attention if the health care system is to be improved. This paper will highlight how Moore successfully exposes the frauds and the scandals in the health care system. A documentary that seeks to make a revelation of an existing failed system should present facts and accurate statistics. It is wrong to make false accusations that lack evidence of proving the claims. This is what is expected in Moore’s film. For it to qualify as a successful documentary, it is critical to analyze whether Moore uses facts and provides evidence for all the claims that he makes. In addition, the claims made by a documentary should be compelling and strong enough to influence policymaking. This is the reason why producers should look for substantial evidence that can influence policy making in the end. The purpose of the documentary should remain evident and the producer should stay from propaganda. The integration of the producer’s opinion with voices from people considered as an authority in a specific field serves to validate the claims made in the film (Moore). Moore’s film can be analyzed based on these criteria in an effort to ascertain that he succeeds in making a documentary that exposes the failure of the health care systems. Evidently, Michael Moore presents facts in his film. He uses statistics to explain the percentage of Americans who lack insurance. He also highlights that over 45 million Americans have insurance covers that prove inadequate when they need medical care

Analyse Marcelo Brodskys Work Buena Memoria From the Perspective of Essay

Analyse Marcelo Brodskys Work Buena Memoria From the Perspective of Memory Work - Essay Example This essay stresses that general Jorge Videla seized power in another coup. Marcelo Brodsky, an Argentine who was both a human rights activist, and an artist, and who was residing in Argentina by this time, went into exile in Barcelona. It is while there that he took keen interest and learnt photography. He returned to Argentina in 1984, after the fall of the dictatorial leadership. The memories of the atrocities meted on his people were still fresh in him. In 1996, Brodsky thought of creating a memory bridge between his own memories and the future generations This paper makes a conclusion that the analysis of the importance of Marcelo Brodsky’s work from the memory perspective. It has been demonstrated beyond doubts that an individual memory can be presented artistically, and be carried forth to generations. This can be shared with other people who may not have been there when the events occurred, but can create a lasting impression, and at the same time communicate the past to them. This in turn brings in transition, and builds a memory bridge from the living memory to the post memory, which benefits generations. It also emphasizes the fact that for a community to effectively handle its present and future predicaments, it must have a special place for the historic events, which would help them make sound judgements. These historical events are the button that must be handed over in an effective manner to other generations.

Analysis of Data Security in Wireless Networks

Analysis of Data Security in Wireless Networks Chapter 1: Introduction Research Method Research is defined as search for new knowledge or an art of scientific and careful investigation of new facts. Research method is referred as a systematic methodology of defining and re-defining the problems, suggest solutions, formulate hypothesis, evaluate the data, make deductions and then reach conclusions. At last, test the conclusions to determine whether they are suitable for the formulating hypothesis or not (KOTHARI, C. R., 2005). The research method chosen for the present study are case studies. Case study research is used because of its capability to bring a clear idea on any complicated issue and thereby strengthening the previously developed research works. A key characteristic of case study research method is its ability to provide multiple sources of evidence each with its strengths and weaknesses (Bill Gillham, 2000). The steps involved in case study research method are as follows: Getting Started The research work started with the collection of data on Wireless Sensor Networks. Sensor networks are referred as secured networks if they can provide end to end security with authenticity and confidentiality. The present research work emphasizes the importance of providing data security in sensor networks through Location-Aware End-to-end Data Security system. Selecting Cases Selection of cases is an important aspect of building theory from case studies. The earlier stages of the research work focused on various security systems and then identified Location-Aware End-to-end Data Security system for providing data security in sensor networks. Literature review section of this research work will explain all these aspects very clearly. Case study research method is quiet difficult as it provides multiple sources of evidence in its research. So to develop this research work, data was collected from various sources like books, journals, articles and online websites. Crafting Instruments and Protocols After the collection of data related to sensor networks and its importance in the field of providing security for networks it was analyzed that efficient steps must be followed by the organizations to provide security for sensor networks. In order to provide an efficient data security system for sensor networks, the research work was customized a number of times. All the design principles were considered for improving the security in sensor networks so to implement better communication networks. Entering the field After gathering the information related to wireless sensor networks from various sources like websites, journals, articles and books. The information gathered gave a better understanding on Location-Aware End-to-end Data Security system for providing data security in sensor networks. Analyzing data The case study research method primarily concentrated on Location-Aware End-to-end Data Security system for providing data security in sensor networks. The data collected for this research work was analyzed using various methods and techniques. This analysis helps to find the link between the research objects and outcomes with respect to the present study thereby providing an opportunity to strengthen the research findings and conclusions. Shaping hypotheses The task of shaping hypotheses is mainly applied for the alteration or modification of models applied for the research work previously. The new models applied in the research depend upon the data analysis. Enfolding literature After the analysis stage which was helpful in assessing the proposed solutions related to the problems occurred by disasters then a detailed critical analysis will be presented in literature review section that will evaluate the existing security designs so as to improve the performance of sensor networks. Reaching closure From the start of the research work to the analysis stage it was analyzed that providing efficient security for sensor networks is very important as it increases the life of networks and improves the efficiency of networks. Background study of Wireless Sensor Networks Wireless Sensor networks will fall under the category of modern networking systems. It has emerged in the past and caters the needs of real world applications. These networks are the preferred choice for the design and development of monitoring and control systems. In the year of 1940s and 50s wireless sensing technology was developed. To discover and chase enemy craft this was used by military (Shimmer, 2006). The technology formulated to let in radio frequency identification and real time location system but the real force behind wireless sensor network was the power to place detectors in remote or in the environment without wired lines. This allows in turn for capture and analysis of information to transmit warnings and to identify the approaching phenomenon. The quality of life by allowing real time information was developed by WSNs. WSNs supply real world information in a perceive manner rather than a virtual world (Shimmer, 2006). As the health of the people is becoming worse a nd the global population is getting older, with the ability to sense and perform direct measurements biometric solutions can be created which will improve the healthcare and improves the quality of life. As one of the key drivers for wireless sensor networks data will be captured and analyzed for detecting and predicting the phenomena like falls and warnings to develop intelligent solutions for industry. Chapter 2: Literature Review 2.1 Overview Providing security for data in Wireless Sensor Networks (WSNs) is a difficult task because of complexity in managing the critical resource. Data security in sensor networks can be achieved by Location-Aware End-to-end Data Security system. A sensor network can called as secured if it can provide end-to-end security through data confidentiality, authenticity and availability. Applications like wildlife monitoring, manufacturing performance monitoring and military operations use wireless sensor networks. Security is the most important requirement for all these WSNs applications. Providing security in wireless sensor networks is different from traditional approaches because of resource limitations and computation restrictions. Node compromise attacks, DoS attacks and resource consumption attacks are the most general attacks in the wireless sensor networks while providing security to the data. This research concentrates on wireless sensor networks, data security in sensor networks, Locat ion-Aware End-to-end Data Security (LEDS) systems and its performance in providing data security. 2.2 Wireless Sensor Network Wireless Sensor Network is a fast growing technology and has exciting research area. Military and civilian activities can be operated successfully using this network. Interconnection between thousands of sensor nodes in large sensor networks can create technical issues (LEWIS, F. L., 2004). To offer a high quality sensing in terms of space and time the sensing nodes are closely arranged and are made to work together. This technology is responsible for sensing and also for the first stages of the processing hierarchy. Computations, communication capacities, memory, low cost devices which have limited energy resources are included in the network. One of the major applications of sensor networks is actuators. This type of sensor networks is widely used in many sectors like military applications, environmental applications and commercial applications (RAGHAVENDRA, C. S., Krishna M. Sivalingam and Taieb F. Znati, 2004). Networks can be organized in multi-hop wireless paths and large lands capes in order to recognize the events of interest. Industries attain security and safety by making use of wireless sensor networks. This network uses sensors for the detection of toxic, harmful and unsafe materials and also provides a way for the identification of leakages which may cause dangerous results. These networks are best suitable for monitoring and help in controlling rotations in moving machinery (Edgar h. Callaway, 2003). Wide usage of sensor networks in large applications forces the network to provide security for data in order to operate the applications effectively. Security is the major issue faced by wireless sensor networks. The main reason for security problems in sensor networks is hold of data by attackers. If number of nodes increased in communication then there may be chance for tampering the data which may create the problem of data loss (CHAN, H. and PERRIG, A., 2003). This sensor network helps in expanding the internet into physical space. Compared to customary approaches wireless sensor networks provide many advantages. Information in sensors networks is available only at runtime. Sensors networking is done by contribution from signal processing, database and information management, embedded systems and architecture and distributed algorithms. Much number of sensors is already in use for monitoring the traffic in networks (Feng Zhao and leonidas J. Guibas, 2004) The organization growth reduces internally by loss of important data and due to false data introduced by hackers in network.However, the lack of end-to-end security guarantee makes the WSN weak due to the attacks. Functions in the networks are injured by internal attacks which lead to breakdown of mission-critical applianc es (Elaine Shi and PERRIG, A., 2004). Hence from the above discussion it can be understood that wireless networks leads to a new trend as the way of interchanging of data through internet service like e-mail and data file transfers is increasing tremendously. WSN is used in many martial appliances. As these networks provide many benefit for organizations and users it lacks in providing security to data while transferring. Wireless sensor networks play a vital role in transferring the data from one network to another without any delays or disturbances. The functionality and behavior of the WSN are completely dissimilar from the other wireless network devices present in WSN.WSN are not assured by the users. In terms of battery and power these devices are much more restrained. The WSN can be separated into two parts Data acquisition and data dissemination network. Data acquisition network consists of sensor nodes and base stations. Sensor nodes are the accumulation of small devices wit h the charge of assessing the physical information of its setting, and base stations are influential devices in case of gathering information of its surroundings. Sensor networks are mainly projected for real-time collection and analysis of low level data in aggressive environments (Javier Lopez and Jianying Zhou, 2008). For this reason they are well fitted to a significant amount of monitoring and observation applications. Famous wireless sensor network applications involve wildlife monitoring, bushfire response, military command, intelligent communications, industrial quality control, infrastructures, smart buildings, traffic monitoring and examining human heart rates etc. greater part of the sensor network are spread in aggressive environments with active intelligent resistance (Feng Zhao and Leonidas J. Guibas, 2004). Hence security is a crucial issue. One obvious example is battlefield applications where there is a pressing need for secrecy of location and resistance to subvers ion and destruction of the network. 2.3. Evaluating the existing security designs in WSNs Evaluation of existing systems can be done with the help of data security requirements like data authentication, availability and authentication. Security is not provided efficiently by the existing systems due to weak security strengths and is exposed to many different attacks. Security authentication tools such as authentication and key management. These tools provide various security mechanisms for sensor network. Routing and localization are supports sensor network (Donggang Liu and Peng Ning, 2007). Similar to the traditional networks most of the sensor network applications need security against introduction, and modification of packets. Cryptography is the standard defense. Interesting system tradeoffs grow while comparing cryptography into sensor networks. For point-to-point communication, continues cryptography attains a high level of protection but involves those keys to be set up among all end points and be in companionable with passive participation and local broadcast (C. S. Ragahavendhra, Krishna M. Sivalingam, Taieb F. znati, 2004). Link layer cryptography with a network wide shared key simplifies key setup and supports passive participation and local broadcast but intermediate nodes might alter messages. The earliest sensor networks are likely to use link layer cryptography because this approach supplies the greatest ease of deployment among presently available network cryptographic approaches. Subsequent systems may react to demand for more security with more advanced use of cryptography. Cryptography implies a performance cost for extra computation that frequently gains packet size. Cryptographic hardware support increases efficiency and also increases the financial cost of implementing a network. Limitations of existing key management schemes From many past years many different pre-distribution schemes have been proposed. Hop-by-hop is one of the techniques which dont provide end-to-end security in a proper manner. This hop-by-hop not only involves the end points but also have the intermediate components for data forwarding. Hop-by-hop header carries information which should be examined by each and every node along the packet path. As this technique involves each node referencing and processing it becomes complex in analysis of networks (Alberto Leon Garcia and Indra Widjaja, 2004). Data authentication and confidentiality is very much vulnerable to inside attacks and the multi hopping makes a worse while transmitting the messages. The problem of distributing and updating cryptographic is to valid member is known as Key Management. The key management is one of the most important tasks in the cryptographic mechanisms for networks. However the sensor networks, the key management is one of the more challenging network because there may be no central authority, trusted third party, or server to manage security keys. The key management performed in the distributed way. The self organization scheme to distribute and manage the security keys proposed (Yang Xiao, 2006). This system certificates are stored and distributed to the user by themselves. False data filtering and their analysis This helps in protecting data from validation in WSNs. Data that is not authorized will be filtered out by the transitional nodes. Location Based Resilient Secrecy (LBRS) is the proposed scheme that identifies the problems and errors in Statistical En-route Filtering (SEF) and Interleaved Hop-by–Hop Authentication (IHA). All these methods are highly exposed to interference attacks and selective forwarding attacks (kui Ren, Wenjing Lou and Yanchao Zhang, 2008). SEF helps in detecting and dropping the false reports during the forwarding process that contains Message Authentication Codes (MAC) generated by multiple nodes (Anne-Marie Kermarrec, Luc Bouge and Thierry Priol, 2007). IHA identifies the fake reports by using interleaved authentication 2.4. Data Security Requirements in Wireless Sensor Networks (WSNs) As wireless sensor networks usage is increasing in organizations, security should be provided for data in order operate organizations successfully. Data security in wireless sensor networks includes data authentication, data availability and data confidentiality. Data should be available for authenticated users only in order to provide security. Various data security requirements for wireless sensor networks are (Kui Ren, Wenjing Lou and Yanchao Zhang, 2008): Data availability Data Confidentiality Data authentication Data integrity Time synchronization Secure Localization Data availability – To ensure availability of message protection in sensor network it should protect the resources or sensor nodes. Nodes in sensor networks should be guarded from unnecessary processing of messages. Avoiding unnecessary processing can reduce the energy usage so that the life time of sensor network increases. Wireless sensors are influenced by many factors like limited communication capabilities and computation. Wireless sensor networks are vulnerable to various attacks like Denial of Service attacks, node compromise attack and resource consumption attack (Shinqun Li, Tieyan Li and Xinkai Wang, 2002). Hence, in order to provide availability and security resources should be maintained effectively. Data Confidentiality – In wireless sensor networks confidentiality can be achieved by allowing only authenticated users to access the data. In sensor networks data can be secured by using cryptographic methods. Using encryption and decryption for data allows only authenticated users to access the data. Unauthorized or third parties cannot read the original data if confidentiality is provided effectively (Chris Karlof, Naveen sastry and David Wagner, 2004). Hence to have confidentiality for data wireless sensor networks should make of encryption methods. Data authentication – Authentication is necessary for controlling the sensor networks effectively. Data authentication in sensor networks allows the users to verify whether the data is sent from authorized resources or not. It also protects the original data from alterations. Digital signatures can be used for authentication in sensor networks (Mona Sharifnejad, Mohsen Sharifi and Mansoureh, 2007). Hence, authentication in sensor networks can be achieved with digital signature which helps in authenticating the senders. Hence from the discussion it can be given in order to provide security data availability, authentication and confidentiality should be sustained in sensor networks. Data Integrity Data integrity in sensor networks is required to check the dependability of the information and concerns to the capability, to support that message has not been corrupted, altered or changed. Even if the network has confidentiality measures, there is still a possibility that the data integrity has been compromised by alterations (Richard Zurawski, 2006). The integrity of the network will be in trouble when the malicious node present in the network throws fake data. Wireless channel cause damage or loss of data due to unstable conditions. Hence from the above it can be given the information provided by the sensor network is easily corrupted which can leads to loss of data. Time Synchronization Most of the sensor network applications trust on some form of time synchronization. Moreover, sensors may wish to calculate the continuous delay of a packet as it moves among two pair wise sensors. For tracking the applications a more collaborative sensor network may involve group synchronization. Secure Localization The usefulness of a sensor network will trust on its ability of each sensor to accurately and mechanically locate in the network (G. Padmavathi and D. Shanmugapriya, 2009). A sensor network planned to locate faults and it need accurate fixed information in order to identify the location of a fault. In this an attacker can easily misrepresent non secured location information by giving false signal strengths and playing back signals. Hence from the above content it has discussed about the security goals that are widely available for wireless sensor networks. 2.5. Proposing Location-Aware End-to-end Data Security (LEDS) LEDS helps in providing safety to data in a well-organized way. Security to data is provided through confidentiality, authentication and availability in LEDS. This mechanism has the ability to provide en-route filtering and end to end authentication. It makes use of key management for achieving data security. LEDS can be used either in small networks or large networks (Ed Dawson and Duncan S. Wong, 2007). LEDS splits the whole network into small cell regions and sends keys for each cell in order to provide security. Cell size of LEDS depends on the number of keys distribute and it does not support dynamic topology. Sensors helps in finding events that are occurring in network. Encryption of events is happened in networks by sensor nodes which are participating in the network. In order to encrypt the events LEDS uses the pre distributed cell keys (Abu Shohel Ahmed, 2009). Sensor nodes calculates unique share key for sensors after encrypting the data, where this is demonstrated using d ifferent sinks. Sensor nodes use authentication keys for calculating MACs. To avoid duplicate reporting each and every report is given with different MACs. A report or data validity will be checked at each and every node while broadcasting through networks in order to provide data security (Fan Ye, Hao Yang and Starsky H.Y. Wong, 2006). Hence from the above discussion it can be understood that, LEDS mechanism helps wireless sensor networks in providing end to end security. This mechanism makes use of key management in order to provide data authentication, confidentiality and availability. The main aim of designing LEDS is to provide end to end data security through data confidentiality, authenticity and availability. LEDS has the capability of preventing false data report attacks. Brief description of the goals of designing LEDS: Provide end-to-end data confidentiality and authenticity: Event reports in wireless sensor networks can maintain authenticity and confidentiality if the sending nodes themselves are not compromised for data corruption. Compromised nodes may affect the neighbor node performance. Cryptographic methods are used to protect data from attackers which is collected from compromised nodes. Key management assists in providing data authenticity and confidentiality by LEDS (Jun Luo, Panos Papadimitratos and Jean-Pierre Hubaux, 2007). In LEDS key management mechanism the nodes use keys for applying cryptographic methods on data in order to provide security. Achieve high level of assurance on data availability: If any attack occurs on data in wireless sensor network, then it should be flexible in selecting alternative ways for forwarding the data. In order to ensure availability, networks should be able to detect and drop the duplicate reports in an efficient and deterministic manner (Kui Ren, Wenjing Lou and Yanchao Zhang, 2008). LEDS assures data availability in the networks by identifying the duplicate reports early in the networks. Hence from the discussion it can be understood that, LEDS was designed for providing security in the wireless sensor networks. False information reports can be eliminated by using some LEDS mechanisms in networks. 2.6. Components of Location-Aware End-to-end Data Security To provide data security, LEDS makes use of two major components: Location-aware key management framework. End-to-end data security mechanism. LEDS provides end to end security by providing data authentication, confidentiality and availability. 2.6.1. Location-aware key management framework As wireless sensor networks are used in wide range of applications it should be deployed correctly in order to collect data. Network planners should give a framework before organizing in order to have security to data. LEDS makes use of key management in providing framework for the sensor networks. Using Key management in LEDS exploits the static and location-aware nature of wireless sensor networks (Reihanah Safavi Naini, 2008). Key management adopts a grid structure for redistributing and examining specific properties related to designing process. For providing a light-weight and robust location aware key management framework for sensor nodes in network preloaded keys are distributed in networks. This framework can be understood through embedding location information into the keys. Framework using key management should be derived in such a way that it should provide data authentication, confidentiality and availability (Yan Zhang, Honglin Hu and Masayuki Fujise, 2006). In LEDS ever y sensor node computes three different types of location-aware keys for distributing purpose. A sensor node computes two unique secret keys which can be shared between a node and sink. These keys help in providing node to sink authentication. A cell key will be distributed between two nodes in the same cell. Confidentiality to data in Wireless Sensor Networks is given by distribution cell keys among network elements. A set of authentication keys can be distributed among the nodes in the network in order to provide authentication to the nodes. This distributing of keys can help sensor networks in data filtering. A Sensor node in the network computes the location-aware key independently. Key management provides basis for end to end data security (Kui Ren, Wenjing Lou and Yanchao Zhang, 2008). Key management strategies for wireless sensor network have proposed recently existing keys which are based on pre-distribution where a probabilistic access for fixing up session keys among adjace nt nodes. Random key Pre-distribution schemes are dangerous to selective nodes and node replication attacks. These frequent attacks can be prohibited by the location aware key management. More challenges are to be taken by the location aware key management such as connectivity within the groups, deployment flexibility and security resilience (Xiaofang Zhou, 2006). Existing strategies need the deployment data as a priority before the deployment. This makes it very hard in major applications. Hence from the above discussion it can be concluded that, for developing a structure for WSN LEDS uses the key management technique. In this framework the safety to data is given by the distribution of keys between sensor nodes. Different location-aware keys computed from sensor nodes can provide data confidentiality, authentication and data filtering. 2.6.2 End-to-end data security mechanism Security is the main issue in transformation of data over internet or any wired or wireless communication. Several encryption methods are implemented and deployed in organization for providing security to data. Network smart cards supports networking mainstream standards and secured protocols. Private data can be sent from smart cards to remote server by establishing a secured connection between network smart cards and trusted remote internet server. This mechanism helps in avoiding manual type for confidential information. End-to-end mechanism struggle in identifying threat mechanism that will capture the data before it is encrypted (Yuliang Zhenq, 2004). Specificdevices and protocols can be installed at the end point connection for offering end to end security. Hyper text Transfer Protocol (HTTP) connection is an example of end-to-end connection to web server where an IP security is used as end-to-end security. There is an opinion that end-to-end security mechanism provides solutio ns in providing security to network based systems. Wireless sensor networks usually consist of a prominent number of resource constraint sensor nodes which are distributed in neglected uncongenial surroundings, and therefore are displayed to more characters of serious insider approaches due to node cooperation. Existing security designs generally supply a step by step security prototype and are exposed to such attacks (Claude Castelluccia, 2005). Moreover, existing security designs are also exposed to several DOS attacks such as report disruption attacks and selective forwarding attacks and thus put information accessibility at stake. To overcome these exposures for major static WSNs come up with a location-aware end-to-end security framework in which secret keys are bound to geographic locations (frank Stajano , Catherine Meadows, Srdjan Capkun and Tyler more, 2007). This location alert property successfully limits the impact of settled nodes only to their locality without involvin g end-to-end data security. The suggested multi functional key management framework checks both node to sink and node to node authentication along with the report forwarding routes and the suggested data delivery access assures effective en-route fake data filtering, and is highly influential against DOS attacks. In end-to-end security the end points refers to connection between client and server. Providing security is the major constraint for transferring data in a secured manner. For providing end-to-end secure communication constrains components like (Michael H. Behringer, 2009) Identity- which helps in identification of entities at both the ends Protocols- to provide required security functions protocols are implemented with the help of algorithms. Security- the end points used by network should be provided with secured protocols and the operations implemented on the end points should be in a secured manner. Thus from the above context it can be given that networks which uses end-to-end security mechanism provides a great security. In spite of having some potential problems end –to-end security many of the organizations are deploying this type of mechanism. End-to-end security protocols and their clarification acts as keystone in having security for the networks. 2.7. Security and performance analysis of LEDS Location aware End to end Data security design (LEDS) function is to anticipate the security and analyze in diverse etiquette. Digital systems afford the sanctuary by means of sundry techniques. In providing the security features researchers generate innovative services for improving the recital and trustworthiness of single technique algorithm (Sam Brown, 2002). Along with security the performance, hardware and software implementations are focused, transparency of the requirements as well as performance and productivity. The factors that involves in escalating this technology are Viability, power consumption, area, complexity, Flexibility. Security analysis can be explained in three dissimilar ways (Kui Ren, Wenjing Lou and Yanchao Zhang, 2008): Data Confidentiality as the security strength Data Authenticity Data Availability Data Confidentiality as the security strength: The requirement of provide data confidentiality within the internal network can be met using the same deployment and management approaches used. Using of the data encryption standard the confidentiality of encryption could be obtained. Data Confidentiality is also used in the Marketing and Sales (John W. Ritting House and James F. Ransome, 2004). In LEDS every report is encrypted by the corresponding cell key and therefore no nodes out of the event cell could obtain its content. Node from the event cell is compromised as the attacker obtains the contents of the corresponding reports because of the data confidentiality. Scheming total network cells number of compromised nodes and portion of compromised cell were utilized. There are two ways for calculating they are Random node capture attack and selective node capture attack. The above figure shows the data confidentiality in LEDS. One has to be clear that in compromising 40% of total cells at least 5% of the total nodes are to be compromised. Along with random node capture attacks accessible defense designs in which compromising a few hundred nodes usually compromise even in all the network communication, which specifies the dominance of the altitude in litheness. Data Authenticity By using diverse online techniques authenticity of data is accomplished. Significance of the data generation determines the position of the obligation (Chris Mann and Fiona Stewart, 2000). Security strength of LEDS regarding the data Authenticity is obtained by the content o
