【摘要】 无线网状网络(Wireless Mesh Network,简称WMN),作为一种新型网络结构形态,被纳入2004年的802.16、802.16e和即将制定的802.11s标准。无线网状网的自组织性、自愈性,有效的移动用户管理和跟踪机制,高容量和高速率的特性,迫切需要高性能的路由算法。论文提出了一种无线网状网络的路由算法WIME( Wireless Intelligence Mesh network routing)。WIME路由算法借鉴AODV路由协议的无线网状网路由协议,以多跳的无线网状网络体系结构为基础,通过按需路由和泛洪控制来寻找路由。新的路由准则结合路由发现与维护等过程,支持基本的路由寻找和异地子网的终端相互通信并具有良好的路由特性。论文在研究中实现了WIME算法的仿真,实验结果验证了该算法具有良好的路由特性,实现了冗余路由的去除,实现了不同子网终端的通信。更多还原

【Abstract】 WMN (short for Wireless Mesh Network), is a new structure of the network and is accepted by the 802.16, 802.16e and the future 802.11s protocol standard. The self-organize, self-aid and effective management of the mobile users need a high-performance routing algorithm.A wireless backbone-based Distributed mesh network routing protocol(WIME) based on Ad hoc demand distance vector, which is suitable for middle scale wireless mesh network, is proposed in this paper. The protocol can supports two wireless clients in different BSS (Basic Service Set) communicate with each other by wireless relaying. Redundancy messages can be significantly reduced by exchanging load information between central nodes and loop path is eliminated.The paper implements the simulation of the WIME algorithm. The result of the study validates that the algorithm has high routing performance while reducing the redundant route and implementing the communication between terminals in different subnet.更多还原
