摘　　要：在对混合无线Mesh路由协议(hybrid wireless Mesh protocol,HWMP)深入研究的基础上,针对目前HWMP协议中两个节点之间存在最短路径也要通过根节点进行数据转发的问题,以及当先验式生成树建立后网络中存在多个核心节点,在这些核心节点上会有多个数据流通过的特点,提出在原来HWMP协议的基础上加入本地链接库(local association base,LBS)及流间网络编码的改进方案。仿真结果表明,改进的HWMP协议降低了数据包的端到端时延,提高了网络吞吐量和数据包投递率。Having deeply studying the hyhrid wireless Mesh protocol （HWMP） of wireless Mesh networks, to sotve the problem that data forwarding needs to go through the root in the routing protocol HWMP even though the shortest path between two nodes exists, and according to the characteristic that many core nodes existing in the network that many data flows go through after building the priori spanning tree, an improved scheme adding the local association base （LBS） and the coding of the intraflow to the original protocol HWMP was put forward. The results of simulation show that the improved HWMP reduces the end- to-end packets delay, improves the network throughput and the rate of packet delivery.
