ABSTRACT
To enable group communication in these scenarios, a number of ad hoc network routing protocols have been proposed. In making the transition from wired to wireless networking, protocol designers have focused on the obvious challenges
of designing a multicast routing protocol that can cope with a mobile environment. As a result, the main goal of most ad hoc multicast protocols is to build and maintain a multicast tree or mesh in the face of a mobile environment, with fast reactions to network changes so that the packet loss is minimized.
