An Efficient Trust based Privacy Preserving Data Aggregation in Wireless Sensor Networks

Abstract

Wireless Sensor Network (WSN) is composed of huge number newlineof battery powered sensor nodes placed in a wide / remote area of newlineinterest. They are authoritative for pass on the real-time data in newlinedetermined monitoring environment to the base station, in which, it will newlinebe processed considerably and examined. WSN is widely used in newlineweather forecasting, habitat monitoring, agriculture, disaster newlinemanagement, telemedicine and in military applications. newlineIn nuclear power plant, WSN is used for loose parts newlinemonitoring, monitoring of radiation level in the environment, vibration newlineanalysis of the reactor core and the primary circuits and requires newlineauthenticity assurance, confidentiality, availability and integrity. In newlinemilitary, WSN is used for dispersal of commands, Data logistics, newlineintelligence and observed data from sensors and for supervising their newlineactivity in isolated areas and strengthening security. Being facilitated newlinewith suitable sensors, these networks can empower the identification of newlineenemy force, their migration and evaluation of the movement and their newlinegrowth. newlineMajor vulnerabilities in WSN are eavesdropping, spoofing, newlinemessage integrity, denial of service, geo location and physical newlinecompromise. Hence it is mandatory to provide end-to-end message newlinesecurity in WSN. Also, another major concern is the need for energy newlineconservation in WSN. Though considerable research is carried out in newlinethis area, a well-organized privacy preserved data aggregation is yet to newlinebe evolved. newlineix newlineThis research work titled An Efficient Trust Based Privacy newlinePreserving Data Aggregation in Wireless Sensor Networks comes up newlinewith the development of efficient protocol schemes so as to enrich the newlinelifetime of the WSNs. A comprehensive study of the overview of newlineliterature sets out as the foundation for accomplishing familiarity newlineregarding the appropriate scenario, the problems encountered and the newlineapplication of the WSNs. Therefore, various methodologies for privacy newlinepreserving aggregated data are suggested in this work, mainly, Trust newlinebased Data Aggregation Protocol
