基于分组管理的无线mesh网多信道分配算法*

为了合理利用多信道来提高无线网络吞吐量，针对基于802.11标准无线mesh网的业务特点，提出了基于分组管理的分布式多信道分配算法。该算法将节点接口分为回程接口与转发接口,并使回程接口分配到在干扰区域内干扰值尽可能小的信道。仿真实验结果表明，该算法可以减少区域干扰,并可充分利用信道的多样性和得到较高的网络吞吐量。

Multi-channel allocation algorithm of wireless mesh networks based on group management

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.
