Energy efficient communication in mobile ad hoc networks (MANET) is a very stringent issue due to the power-constraint in each mobile node. Thus designing a suitable energy efficient multicast routing protocol for optimum use of existing power and to render good system performance simultaneously is a real challenge. In this paper, we proposed a routing algorithm for multicasting that ensures efficient utilization of power for each mobile node. The reliability issues are also addressed within Power Aware Multicast on-demand Routing (PAMOR) through the provision of multipath between a pair of nodes. Provision of multipath not only increases the reliability of the network but also helps to use equivalent paths for load balancing within MANET. Moreover, multipath can also serve as an alternative path in case of link breakage while avoiding an extra overhead for path discovery methods. Thus the proposed protocol PAMOR is expected to perform satisfactory in terms of power consumption as well as for bandwidth utilization. © 2010 IEEE.
