Secured Greedy Geographical Reliable Reactive Routing for WSN

Bhramitha B Shetty | Manimozhi Iyer

Abstract: Providing secure, reliable and energy efficient communication under fading channels is one of the major technical challenges in Wireless Sensor Networks (WSN). In this paper, we present the Greedy Geographical Routing inorder to increase the resilience to link dynamics for WSNs and also increases the packet delivery ratio, throughput and energy efficiency. Here the main idea is to find the guide path by Greedy Geographic routing, which determines the guide path that has shortest distance to the destination through which the packets are greedily progressed towards the destination. Specifically, we introduce Signature Signing inorder for the secured transmission of the sensed data to the sink. Through extensive simulations, we demonstrate that compared to other protocols such as AODV based R3E, Greedy Geographic Routing remarkably improves the packet delivery ratio and achieves efficient performance, less delay and also lower energy consumption since the overhead is reduced.
