An Energy Constrained Multicast Routing Protocol in Ad Hoc Networks

The multicast ad hoc on-demand distance vector (MAODV) protocol which is multicast operation of the ad hoc on-demand distance vector (AODV) routing protocol enables dynamic, self-starting, multihop routing between participating mobile nodes wishing to join or participate in a multicast group within an ad hoc network. By analyzing the operation mechanism of MAODV, this paper presents an energy constrained multicast routing protocol-ECMRP. By making proof of correctness and complexity analysis of ECMRP,this paper simulates the two routing protocols MAODV and ECMRP, the results show that ECMRP has a better delay than MAODV and a more balance in energy consumption. On the one hand, it saves the energy of the network system; on the other hand, it has a longer network lifetime than MAODV and successfully solves the inconsistent question of energy and delay.
