A MANET is a self-conFigureuring system of mobile hosts connected by wireless links. The routers are free to move randomly and organize themselves arbitrarily; thus, the network's wireless topology may change rapidly and unpredictably. Routing is the process of exchanging information from one station to the other stations of the network. Multicasting is a popular mechanism for supporting group communication. In a multicast session, the sender transmits only one copy of each message that is replicated within the network and delivered to multiple recipients. This multicast routing is highly deal with self-organized network in recent days due to its broadcast characteristics. However, devising multicast protocols to provide group communications in mobile ad-hoc networks is significantly more complicated, because of the wireless medium, changing topology, battery power and available bandwidth as well. This paper, evaluates two prominent on-demand multicast routing protocols for group communication, namely, Multicast Ad hoc On-Demand Distance Vector (MAODV) and On-Demand Multicast Routing Protocol(ODMRP) as increasing number of multicast sources and receivers in both single-active multicast group and multi-active multicast group in the network.
