Abstract: Mobile ad hoc network is a collection of wireless node and this network is self-organising and configures multi-hop network. Basically each mobile node will be operated on battery. So for transmission and reception it will consume the nodes energy. Because of limited power it will drain faster. So to provide energy-efficient route between source and destination, the routing protocol must consider the residual energy of the node. In this paper, we first introduce an energy model to calculate the energy of the node than we propose the energy-efficient routing protocol by modifying the packet structure of AODV protocol. The performance of proposed protocol is analysed by using performance metrics that is routing overhead, energy consumption, end to end delay and packet delivery ratio.
Keywords: mobile ad hoc network, multi-hop, AODV, unicast.
