摘　　要：The major challenge faced by wireless mesh networks is the capacity reduction caused by interference,and interference can be reduced or even eliminated through appropriate channel assignment.This article presents a comprehensive survey of channel assignment schemes for multicast in multi-radio multi-channel wireless mesh networks.We analyze the state-of-the-art channel assignment schemes for multicast and provide comprehensive taxonomy of the latest work.In general,we classify the channel assignment schemes for multicast into two types,that is,sequential multicast routing and channel assignment(SMRCA)and joint multicast routing and channel assignment(JMRCA).Detailed review of channel assignment schemes in each category is provided.Possible future research directions and corresponding solutions are also explored to motivate research interests in the field of channel assignment for multicast in wireless mesh networks.The major challenge faced by wireless mesh networks is the capacity reduction caused by interference, and interference can be reduced or even eliminated through appropriate channel assignment. This article presents a comprehensive survey of channel assignment schemes for multicast in multi-radio multi-channel wireless mesh networks. We analyze the state-of-the-art channel assignment schemes for multicast and provide comprehensive taxonomy of the latest work. In general, we classify the channel assignment schemes for multicast into two types, that is, sequential multicast routing and channel assignment （SMRCA） and joint multicast routing and channel assignment （JMRCA）. Detailed review of channel assignment schemes in each category is provided. Possible future research directions and corresponding solutions are also explored to motivate research interests in the field of channel assignment for multicast in wireless mesh networks.
