| 摘 要： | 在新建路由时,AODV选择具有最短跳数的路由,未考虑节点的负载,所选的路径可能造成网络拥塞,且在节点移动较快时,性能下降非常厉害。针对这种情况,对其路由发现和维护阶段进行改进,在路由发现时根据节点负载选择节点并且在拓扑改变时动态对路由进行优化,减少网络拓扑变化对路由的影响。仿真结果证明,改进后的协议在减少网络拥塞、降低丢包率等方面较AODV协议均有了改进。

| Abstract: | When establishing new route,AODV routing protocol chooses route with the minimum hop,without considering the load of node,and when node moves faster,the performance degenerates severely.To address this situation,an improved protocol with improved route discovery and route maintenance phase is presented.It selects route based on the load of node and can optimize the route according to network topology dynamically,to reduce the negative influence of dynamic change of network topology.Results obtained through simulations demonstrate that the improved protocol is better than AODV in reducing network congestion and packet loss rate. |
