ENERGY AWARE ROUTING ALGORITHM FOR WIRELESS Ad-HOC NETWORKS

Abstract

The efficient node-energy utilization in mobile ad-hoc networks has been studied because ad-hoc nodes operate with limited battery power. In ad-hoc networks, nodes perform the function of hosts as well as router as there is no existing infrastructure. Thus, when a node expires one router is lost by network. Hence, increasing network lifetime is one of the important factors in design of ad-hoc networks. Here, AODV is used for further enhancement because of its low overheads and good performance. The AODV protocols perform routing based on the metric of least number of hops. To extend the lifetime of the ad-hoc networks, AODVEA i.e. AODV energy aware routing protocol is used which performs routing based on the metric of minimum remaining energy. In this project, an efficient AODVM i.e. AODV modified routing protocol is proposed which performs routing based on the combination of least hops and minimum remaining energy. The performance of the proposed protocol has been examined and evaluated with the NS-2 simulator in terms of network lifetime, end-to-end delay and energy consumption. The proposed protocol gives less delay and energy consumption than AODVEA and improved lifetime than AODV.
