Reliable On-Demand Multicast Routing With Congestion Control in Wireless Ad Hoc Networks

In this paper, the authors address the congestion control multicast routing problem in wireless ad hoc networks through the Medium Access Control (MAC) layer. They first introduce the Broadcast Medium Window (BMW) MAC protocol, which provides reliable delivery to broadcast packets at the MAC layer. They then extend the wireless On-Demand Multicast Routing Protocol (ODMRP) to facilitate congestion control in ad hoc networks using BMW. Through simulation, they show that ODMRP with congestion control adapts well to multicast sources that are aggressive in data transmissions.
