Secure, Reliable and Lightweight Trust System Which Enhance Security and Energy Efficiency of Wireless Network System

Abstract

In WSN, sensor nodes is the centre of interest which report the cognitive process to the sink by sensing the data, and this report will satisfies the report frequency necessary by the sink. Inside the domain of system security, system deciphers the idea of trust as a connection among entities that take part in different conventions. Trust relations are focused around confirmation made by the past connections of substances inside a convention. In wireless sensor network the resource efficiency and reliability of a trust system are the most basic supplies. Due to the low reliability and high overhead the developed existing trust systems for wireless sensor networks are unable of satisfying these supplies. Therefore there is need to propose a lightweight and reliable trust system which can efficiently decrease the networking consumption while malicious and faulty cluster heads and also exceeds the limitations of traditional weighting methods for trust factors in which weights are allocated subjectively and also insist less communication overhead and memory. In contribution if attack is found in CH then cluster members transfer data to the DCN. Also in this system introduced the method DCN share data with the clusters DCN in tree structure. If attack is found in Data Collection Node (DCN) then Base Station recovered the data from other DCN and prevents data loss. Also in proposed system we used ECH algorithm for clustering process. Due to this system can forward data securely and efficiently and improve the accuracy of the network and minimize the data loss.
