Abstract: Multicast routing protocol play an important role in adhoc wireless networks to provide this communication. It is always advantageous to use multicast rather than unicast especially in the adhocenvironment. In this paper, we propose an enhancement of Neighbor Aware Multicast Routing Protocol, which is tree based, hybrid multicast routing protocol for adhocnetworks. Tree based routingprotocol ensures the robustness. Robustness is one of the issues in designing a multicast routing protocol. The improvement can be helpful to increase the limits the population of forwarding nodes by using trusted dominant pruning method. For route creation the protocol uses neighboring information and trusted dominant pruning approach uses for route maintenance.
