该文针对无线mesh网络性能需求及目前所面临的挑战，研究了先应式的链路状态路由协议OLSR，指出了该协议在选择多点中继集合时可能使某些节点负载过重，导致网络拥塞。提出了一种改进的多点中继集选择算法，高效地实现控制消息在网络中的洪泛，在此基础上，基于改进的OLSR路由协议组建了具有多跳自组织的mesh网络，通过布置实际节点验证了改进的OLSR协议在网络的吞吐量、网络延时等方面都得到了一定的改善，提高了网络的性能。

For wireless mesh network performance requirements and the challenges facing at present , this pa-per describes the proactive optimized link state routing ( OLSR) protocol, points out that the protocol may make some nodes overloaded in selecting multipoint relays ( MPR) set, this leads to network congestion .Then the paper presents an improved MPR set selection algorithm to achieve an efficient mechanism for flooding control traffic, on this basis , based on the improvement of the DSR routing protocol has formed a multiple hops self -organizing mesh network , by the layout of the actual node to verify the improved OLSR protocol has been some improvement in the throughput of the network , the network delay , improve the performance of the network .
