Power Aware Routing in Ad Hoc Wireless Networks

Development of the efficient power aware pro-tocol is the need of today’s adhoc networks. Al-though developing battery efficient systems that have low cost and complexity, remains a crucial issue. In order to facilitate communication within a mobile adhoc network, an efficient routing protocol is required to discover routes between mobile nodes. Power is one of the most important design criteria for adhoc networks as batteries provide limited working capacity to the mobile nodes. Power failure of a mobile node not only affects the node itself but also its ability to for-ward packets on behalf of others and hence af-fects the overall network lifetime. Much research efforts have been devoted to develop energy aware routing protocols. In this paper we propose an efficient algorithm, which maximizes the network lifetime by minimizing the power con-sumption during the source to destination route establishment. As a case study proposed algo-rithm has been incorporated along with the route discovery procedure of AODV and by simulation it is observed that proposed algorithm’s per-formance is better as compare to AODV and DSR in terms of various energy related parame-ters like Total Energy Consumption, Averag
