摘　　要：为更可靠地实行无线mesh网络的资源分配,将干扰模型引入mesh网络的节点流量模型中,提出改进型的基于流量感知的固定C-HYA信道分配方法,采用一种更贪婪的算法规避波纹效应,降低网络干扰。之后对算法进行实现仿真,建立相应网络拓扑结构,对在mesh网络中采用传统算法及改进算法对抗波纹效应及信道干扰的情况进行了对比分析。To ensure the reliability of the wireless mesh network resource assignment, an interference model to node traf- fic model of WMN was introduced, and channel assignment strategy based on fixed traffic-awareness C-HYA channel as- signment strategy was improved, which a greedier algorithm to avoid ripple effect and reduce network interference was adopted. In addition, the network topology and simulates the algorithm was built. The results of theoretical analysis and simulation show the performance of improved channel assignment strategy compared with traditional algorithm in terms of resisting ripple effect and channel interference.
