| 摘 要： | 由于移动ad hoc网络的AODV（Ad hoc on-Demand Distant Vector）协议仅维护1条到目的节点的路由记录,即使路由未失效,在超时后也会被删除,因此提出改进的AODV协议---HI-AODV协议.改进内容为：（1）借鉴DSR协议的特点,使其路由表维护多条路由记录;（2）在路由发现和路由维护中有效利用路由缓存信息和多路径路由,使得路由发现更加迅速.仿真结果表明HI-AODV协议可以提高数据吞吐量,减小平均延时.但由于移动ad hoc网络节点的移动性,采用HI-AODV协议容易导致路由信息失效,对路由协议产生负面影响.

| Abstract: | Only one routing record which indicates the route to the destination node is maintained in Ad hoc on-Demand Distant Vector(AODV)protocol of mobile ad hoc network.Although the routing record is valid,it will be deleted if it is overtime.So the improved AODV protocol,HI-AODV is proposed.The improvement is:(1)Multi-records are maintained in the routing table referring to the advantages of DSR protocol;(2)the routing cache and the multi-path routine are effectively utilized in the process of routing discovery a... |
