针对无线Mesh网中信道分配的适应性欠缺的问题，提出了一种基于权重优化的信道分配算法。该算法引入损耗因子使每次节点博弈的权重自动更新，将传统的静态博弈变为动态博弈，通过非强占优先制排队模型求节点的优先级使得信道分配更加公平。仿真结果表明，该算法在吞吐量和传输延时方面有所优化，验证了信道分配的公平性。

According to the lack of channel assignment adaptability in wireless Mesh network, a channel assignment algorithm based on weight optimization is proposed. This algorithm introduces the loss factor to make the weight of each node update automatically in the game, which changes the traditional static game to dynamic game. The non-preemptive priority queuing model is adopted to get the priority of node, which makes the channel assignment fairer. The simulation results show that the algorithm has better performance in throughput and propagation delay and the fairness of channel assignment is verified.
