In highly dynamic mobile ad hoc networks, there exist transmission problems such as delivering data packets, packet delay, time delay, node mobility and so on, particularly in large scale networks. The existing Position-based Opportunistic Routing (POR) protocol makes use of the stateless property of Geographical routing and the broadcast environment of wireless medium. But this protocol is prone to over heading problem as well as lack of data confidentiality. To overcome this problem, the proposed protocol is Adaptive Demand driven Multicast Routing protocol (ADMR) has been designed specifically for use in the ad hoc network environment.
