为解决经典 AODV(按需距离矢量)路由协议中目的节点在已建立路由链路信号覆盖范围内随机移动时脱离其原来直接通信节点而断路、通信恢复时间长以及网络负载大等问题,对利用 AODV协议 Hello消息报文激活中间节点与目的节点的通信切换实现快速路由修复进行了研究,并得到改进后的路由协议 AODV_L。仿真结果表明,AODV_L比经典的 AODV路由协议减小了网络负载并缩短了路由修复时间。AODV_L更适用于目的节点在已建立路由链路信号覆盖范围内随机移动的网络,节点间通信具有更高的实时性。

In order to minimize such problems as breakdown,long communication recovery time and large network load oc-curred when the destination node in the classical Ad hoc On-Demand Distance Vector (AODV)routing protocol departs from the node originally in direct communication as it moves randomly within the established scope covered by the routing link sig-nals,this article studies the implementation of fast routing repair by activating the communication handover from the interme-diate node to the destination node using the AODV Hello messages,and obtains an improved routing protocol,AODV-L.Sim-ulation results show that this AODV-L protocol reduces the network load and shortens the routing repair time,more suitable for networks that the destination node randomly moves within the scope covered by the routing link signals and that the inter-node communication has higher real-time performance.
