合理地分配信道是提高多信道无线Mesh网络性能的关键。针对动态信道分配策略平均吞吐率较低的不足，采用相对平衡理论，提出了一种基于可通邻居节点可用信道表的信道分配方法，给出了该方法的主要步骤和具体实现过程，并分析了时间复杂度。节点在进行数据发送前，利用可通邻居节点的可用信道集合，建立可通邻居节点可用信道表和信道优先级队列，在此基础上，选取一个最优信道，并使用改进的RTS／CTS协议进行信道协商和数据收发控制。仿真结果表明，提出的方法在平均吞吐率方面提高了5．2％。

The reasonable allocation channel is the key to improve the performance of multi-channel wireless mesh networks.Aiming at the deficiency of lower average throughput in dynamic assignment strategy, combining with the Correlated Equilibrium ( CE) , a channel assignment method based on available channel list of neighbour nodes is proposed, which gives the main steps of the method and the specific implementation process.Before sending data, using the available channel set of neighbor nodes, the node builds an available channel list of neighbor nodes and channel priority queue.On the basis, the highest priority channel is selected.And then a modified RTS/CTS pro-tocol is adopted for channel negotiation and data transceiver control.The simulation results show that the proposed method in this paper increases by 5.2% in average throughput.
