Location Aware Relay Node Placement for Energy Constrained Wireless Sensor Networks

Abstract

In this paper we consider the problem of the Relay Node Placement for sustainable data forwarding in Wireless Sensor Networks where an energy aware relay node deployment model is proposed.The proposed model considers the constrained placement.Hop Constraint and Distance Constraint are the two main constraints considered in this paper for the determination of energy based feasible path for any Sensor Nodes to reach the destination.The main objective of this paper is to reduce the maximum possible number of extra Relay Nodes to be deployed by which the deployment cost will be reduced.Further to preserve the energy of energy constrained Sensor Node; the distance constraint is put forward during the evaluation.Simulations are conducted over the proposed model with varying network characteristics demonstrate the effectiveness in the reduction of deployment cost and energy consumption.
