摘　　要：为解决现有的先验式路由协议不能根据网络负载动态变化的问题,提出动态路由选择和拥塞避让混合路由协议。采用新的路由度量、先验式路由选择方法和拥塞处理机制,根据整条链路的节点负载动态选择最优的路径,实现根据整个网络的负载情况进行动态选择,避让拥塞节点,提高网络的鲁棒性。ns-3的实验结果表明,与区域条件感知混合路由协议(regional condition-aware hybrid routing protocol, RCA-HRP)协议相比,该混合路由协议可以有效改善网络的平均吞吐量、延迟和丢包率。To solve the problem that the existing priori routing protocols cannot change dynamically according to the network load,a hybrid routing protocol of dynamic routing and congestion avoidance was proposed.The new routing metric,a priori routing method and congestion processing mechanism were used to dynamically select the optimal path according to the node load of the whole link,the dynamic selection was realized according to the load of the whole network,the congested nodes were avoided and the robustness of the network was improved.The experiment of ns-3 shows that compared with the regional condition aware hybrid routing protocol(RCA-HRP)protocol,the hybrid routing protocol can effectively improve the average throughput,delay and packet loss rate of the network.
