SECURED AND TRUST AWARE ROUTING SCHEME FOR WIRELESS SENSOR NETWORK WITH THE CONCERN OF PACKET DROPPING ATTACKER NODES

Abstract

In a wireless sensor network, it is very difficult to achieve secured routing because of the unavailability of a centralized unit for investigating and securing the functions performed by the malicious attackers. Triple kay based Selective Dropping Attack Detection method (TK-SDADM) is established in the traditional approach for assuring secure routing. But, this traditional method cannot be able to provide secured transmission of data within the nodes. Therefore, there is a need for a novel method for assuring the highly secured transmission of data by identifying the inside attackers. Hence, a new approach named as Secured and Trust aware Secured Routing Scheme (STSRS) is established. Primarily, trust aware routing is carried out for assuring the secured data transmission. Also, in this approach, optimal shortest route path selection is performed by the Pareto optimality based Particle swarm optimization algorithm. After the selection of path is finished, the data is transmitted securely by using the Triple key-based AES encryption technique. The entire process of this approach is examined using the NS2 simulation platform and so that the output efficiency of this new approach is improved.
