An Enhanced Approach for Finding an Optimal Path in MANET using Energy Aware Reverse Reactive Routing Protocol (EA-RAODV)

– In MANET, ad hoc network is an energetic topology, hosts, and infrastructure less multi-hop wireless ad hoc environment. The efficient node-energy consumption in wireless ad hoc networks is essential as ad-hoc nodes operate with limited battery power. Thus, failure of node in ad hoc network leads to loss of communication in the network and down frequently due to mobility of nodes. It maintaining alive node for longer time i.e. growing network lifetime is one of the important factors in design of ad-hoc networks. In this paper, we introduced energy aware efficient modified RAODV (EA-RAODV) reactive routing protocol is proposed which performs routing based on the combination of least hops, power and minimum remaining energy. An effort has been done to perform analysis and find out optimal path using random way point mobility model. The outcomes have been derived using self created network investigation scenarios for varying parameter of network. The performance of the proposed protocol has been examined and evaluated with NS2.34 Simulator in terms of network lifetime, consumed energy, remaining energy, packet delivery fraction, routing overhead and normalized routing load. Finally we concluded that the proposed protocol i.e. EA-RAODV provides more energy efficient, secure and stable routing strategy for wireless ad hoc networks.
