The Mobile Ad hoc Network (MANET) is a wireless network between the collection nodes which is constructed dynamically without using centralized infrastructure. In MANET energy conservation is one of the important challenge issue to improve the efficiency of the multicast routing in the network. We propose a Received signal strength based Cooperative Multicast Routing Protocol (RCMRP) that implements energy conservative technique over which the life time of every node increases for longer periods without frequent charging. It also ensures low communication overhead and reliable network connectivity. The cross layer framework is designed by combining physical, MAC and network layer. The physical layer provides reliable network connectivity by cooperative transmission. At MAC layer, the nodes are classified into clusters and the cluster head is responsible for inter cluster transmission. The Network layer has RCMRP. The received signal strength value is taken from the physical layer and is used as one of the parameter to make decision on whether to select the link or not, prior to the route discovery process. Because of this, number of route discovery process has been reduced which in turn reduces the energy consumption to great extend. The simulation results are compared with other three protocols such geographic routing protocol, Greedy Perimeter Stateless Routing protocol (GPSR), Cooperative Multicast Routing protocol (COMRoute) in terms of packet delivered, throughput, delay and Residual energy of the communicating nodes. The NS-2 simulation results reveals that the proposed work is energy efficient in reference to increased number of packets delivered and more residual energy of the network.
