Improve Energy Efficiency in AODV

To establish route between nodes, an efficient routing protocol is required to discover routes in a mobile adhoc network. Node energy is one of the important design criteria for adhoc networks due to dynamic topology of Ad Hoc Network. Mobile nodes have limited energy in their batteries. Power failure of a mobile node affects the node itself as well as decreases network performance also due to link failure. Much research efforts have been devoted to develop energy aware routing protocols. In this paper we propose an energy efficient routing algorithm that takes care about stability of network. A new route discovery process proposed in this paper that takes into account the distance between nodes and node battery power to improve energy efficiency in AODV. This will maximize the network lifetime by minimizing the power consumption and decrease the routing overhead. We will implement our proposed algorithm in AODV and performance will evaluate against the original AODV, finally we will study it through NS-2 simulator.
