Mobile ad hoc network (MANET) is temporarily constructed network with no fixed infrastructure. Energy conservation is a critical issue in MANET since batteries are the only limited-life energy source to power the nodes. The multicast ad hoc on-demand distance vector (MAODV) protocol is multicast operation of the ad hoc on-demand distance vector (AODV) routing protocol. This paper presents an innovative improvement of energy aware multicast routing protocol for wireless ad hoc network called Power Efficient Multicast Ad hoc On demand Distance Vector (PEMAODV) routing protocol. The improvement of this protocol in energy performance is obtained by Power Aware (PA) selection mechanism which considers not only the nodal longevity but also the maximal nodal residual energy during the routing process. A comparison of PEMAODV and MAODV routing protocols can be done through simulations. The results show that PEMAODV has a higher packet delivery ratio and smaller end-to-end delay than MAODV and a more balance in energy consumption. Meanwhile PEMAODV prolongs the network lifetime with a small increase of protocol overload.
