| 摘 要： | 从无线链路干扰的角度为802.11s定义的无线Mesh网络提出一种信道分配策略.首先在现有无线干扰模型和传播模型的基础上,通过仿真研究无线干扰对无线Mesh网络性能的影响;然后根据仿真结论提出无线链路干扰模型,同时利用无线Mesh网络流量呈现树状拓扑汇聚的特点对网络拓扑进行有序分解,从而划分出多跳链路干扰和单跳并行链路干扰;最后提出的802.11s信道分配策略的基本思想是采用循环交叉分配信道的方法尽量减少或消除无线多跳链路干扰.

| Abstract: | In this paper a channel assignment strategy based on wireless link interference model for 802.11s wireless mesh network is proposed.At the beginning,existing wireless interference model and transmit model are analyzed,and the impact of wireless interference on wireless mesh network is researched by simulation.According to simulation conclusion a wireless link interference model is proposed,and then considering tree-based netflow,the wireless mesh network topology is orderly decomposed so as to mark off the ... |
