RTS-CTS handshake based protocols achieve "reliable unicast" by eliminating the hidden node problem effectively, however, these solutions are not directly or efficiently generalizable for solving the "reliable multicast" problem; multicast remains a best-effort operation in wireless ad hoc networks. Here we present a simple light-weight MAC protocol, namely Busy Elimination Multiple Access (BEMA) protocol, for solving the reliable multicast problem. BEMA grants on-demand access to the channel - rather than assigning fixed slots as in TDMA based approaches -and supports prioritization of traffic, thereby providing a useful building block for applications with reliability and qualityof- service requirements.
