针对当前最优化链路状态路由协议没有考虑多参数服务质量的缺陷，为提高网络的通信质量，提出一种多参数服务质量的多点中继选择算法。采用延时、带宽、节点的饱和率、链路稳定性等参数构建服务质量评价指标，在多点中继选择时，同时考虑邻居节点的覆盖范围和服务质量参数，在路由选择算法中，综合考虑最小跳数和服务质量参数。采用仿真对比实验对其性能进行分析，实验结果表明，该算法的路由协议有效降低了平均延时、丢包率以及 TC分组数量，提高了网络的吞吐量。

Current optimized link state routing protocol fails to consider multiple parameters quality of service ,to improve the communication quality of network ,a multipoint relays selection algorithm based on quality of service with multi‐parameters was presented .The parameters of delay ,bandwidth ,saturation of node and link stability were used to construct the service quality evaluation index .The parameters of service quality and neighbor nodes coverage were considered in multipoint relays selection while the minimum hops and the parameters of service quality were considered in the routing algorithm .The performance was tested by simulation experiment .The experimental results show that routing protocol based on the proposed algorithm reduces network delay ,packet loss rate and TC packet numbers ,and improves the network throughput .
