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. The authors 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.
