Multicast data communication is an efficient communication scheme, especially in multi-hop ad hoc networks where the media access control (MAC) layer is based on one-hop transmission from one source to multiple receivers. In comparison to unicast broadcasting, multicast through a wireless channel must be able to cope with different channel conditions of multiple users and the mobility of the user to provide good quality to all users. Therefore, several MAC layer protocols have been proposed to provide reliable multicast. However, additional overhead is introduced, as a result, which degrades system performance. In this paper, we propose an efficient wireless multicast MAC protocol with a small control overhead required for reliable multicast in multi-hop wireless ad hoc networks. We present analytical formulations of system performance and the delay associated with overload.
