A Study of Routing Protocols for Energy Efficiency in Wireless Sensor Networks with Mobile Nodes

In Wireless Sensor Networks numerous sensor nodes are distributed over a diverse area to form the networks and doubtlessly the energy resources limit their overall operation. As it is difficult to recharging or replacing the battery of each node, so the energy efficiency of the system is one of the critical issues in designing Wireless Sensor Networks. In this paper, we considered the concept of Topology Control as a layer between MAC layer and routing layer, which has some very important aspects to reduce the energy consumption of Wireless Sensor Networks. In this research study, our main aim was to analyse the performances of AODV, DSDV and DSR routing protocols by simulation and determine the best performing routing protocol based on energy efficiency while considering the idea of Topology Control layer. This paper presents the comparative study of the performance of these three routing protocols on the basis of energy consumption for Wireless Sensor Networks with mobile nodes. Keywords—Wireless Sensor Networks, Topology Control, routing protocols, energy efficient routing.
