A Novel Approach on Energy Efficient AODV Algorithm for MANETs

Miral V. Vora, Prof. Jignesh H. Joshi

MANETs are a collection of unstructured wireless mobile nodes which provides independence and scalability for mobile networks. It is composed of moving mobile nodes that are battery operated. In AODV routing protocol, first of all broadcast the hello message to discover the Neighbor node and then source node broadcast RREQ (Route Request) packet to Neighbor node for finding path to the destination node. If The Neighbor node having less energy, as well broadcast RREQ and it lifetime expires after some certain time (i.e. node goes down), it cannot forward RREP (Route Reply) on reverse path and also cannot carry the data from the source node that?s why source node has to rebroadcast RREQ that results is overhead of the RREQ message, less packet delivery ratio and throughput and more energy consumed. These problem have to be solved so here can proposed energy efficient AODV algorithm based routing protocol. In this paper proposed, source node does not send any data packet; until no enough energy (battery life time) of intermediate node and received RREP of its neighbouring exceeds a particular threshold. In this paper also suggested two approaches for making energy efficient algorithm. The performance of the proposed protocol will simulate with the help of NS-2.34 simulator for various scenario using different parameter, also survey on energy efficient algorithm. At last finally we concluded that the proposed protocol improves energy efficiency, network throughput and network lifetimes.
