Multicasting can be an effective routing service in Wireless Mesh Networks (WMNs), which have gained significant acceptance in recent years due to its potentials of providing a low-cost wireless backhaul service to mobile clients. Many applications in WMNs require efficient and reliable multicast communication, i.e., with high delivery ratio but with less overhead among a group of recipients. However, in spite of its significance, there has been little work on providing such a multicast in mesh networks. Traditional multicasting protocols for wireless multi-hop networks mostly assume that all nodes (equipped with a single interface) collaborate on the same channel.
