摘要： 提出一种改进的路由协议HAODV。该协议在链路中断时，接收中断处的上游节点广播到目的节点的跳数，由于在一定时间内，节点的移动不会太远，因此能快速修复路由路径，同时利用到基础路径的跳数，限制路由信息广播及修复的区域，从而减少广播风暴。仿真结果表明，与AODV协议相比，该协议的包投递率更高，且平均延时及路径节点跳数更少。

Abstract: Based on the hop count of the destination node and the base path, the paper proposes a routing protocol HAODV to improve AODV. HAODV uses the hop count of the destination node to fix the routing path quickly and efficiently whenever the link breaks because the nodes can not move a lot in a period time, and uses the hop count of the base path to reduce the broadcast storm effectively. Simulation results show HAODV is higher than the AODV in packet delivery ratio, less the average delay and less path hop count.
