摘　　要：针对无线mesh网络目前存在的资源查找效率不高,路由跳转过多,网络中节点的通信链路易失效等问题,研究并设计了一种基于Chord的无线mesh网络可靠路由查询机制.该机制将Chord应用于无线mesh网络物理拓扑结构,设计了分层和双向查询模型,并在Chord固有的单路径查找模式上加入可靠多路径选择策略,在节点出现失效或链路异常等情况时启用多路径可靠查询方法,有效提高节点间成功通信概率,并对性能进行了分析.Aiming at the problems of Wireless Mesh Networks（ WMNs） such as lower resource lookup efficiency,much more routing retransmission and easy failure of the communication links among the nodes,this paper proposes a routing query mechanism with reliability under WMNs based on the Chord. This mechanism applies the Chord to the physical topology of WMNs,and designs a hierarchical and bidirectional query model and adds the multi-path routing strategy with reliability based on the original Chord single-path routing mode. When the nodes or links in the network are failed,the new mechanism of the multi-path routing strategy with reliability will be enabled to search the best routingpath to achieve the communication. This mechanism effectively improves the probability of successful communication among the nodes. The performance is also analyzed.
