Abstract:To improve network throughput by using multi-channel properly, proposed distributed multi-channel allocation method based on group management, according to the traffic characteristics of the wireless mesh networks based on 802.11 standards. This method divided the interfaces in node into backhaul interfaces and data transfer interfaces, and could allocate channels to the backhaul interfaces with the least channel interference cost in the interference region. Simulation results show that the proposed method can reduce regional interference, take full advantage of the diversity of channel and get better network throughput. ......
