Energy consumption is a crucial design concern in wireless ad hoc networks since wireless nodes are typically battery-limited. Power failure of a mobile node not only affects the node itself but also its ability to forward packets on behalf of others and hence affects the overall network lifetime. To this purpose, routing algorithms must be developed to discover routes between mobile nodes that energy consumption of nodes is considered as a primary goal. We present an energy and lifetime aware multicast algorithm by route selection strategy to equalize energy consumption of nodes. It can balance individual node’s battery power utilization and hence prolongs the entire network’s lifetime. The scheme has been simulated in various network scenarios to test operation effectiveness in terms of performance parameters such as packet delivery ratio, network lifetime and total consumed energy of network. Also, we compared proposed protocol with ODMRP. We observe from the simulation that proposed protocol performs better than ODMRP.
