| 摘 要： | 针对Ad Hoc网络中按需距离矢量路由协议路由开销大，以及位置路由中位置信息在获取方式上存在的缺点，提出一种位置信息辅助的按需距离矢量路由协议(LAODV)，协议结合AODV以按需的方式获取网络节点的位置信息，并以泛洪、位置信息修正的贪婪转发和局部受限泛洪相结合方式进行路由发现，同时提出了路由维护策略和局部多径备份路由策略。仿真结果表明，LAODV能够获得较好的分组递交率、时延和路由开销性能。

| Abstract: | To decrease overhead of on-demand vector routing protocol and overcome shortcomings of location-aided routings about getting location information,a novel location-aided ad hoc on-demand vector routing protocol(LAODV) is proposed.In LAODV,location information is got on demand.During route discovery,flooding,location correct-based greedy forward strategy(LCGF) and limited flooding in expected zone are combined to improve the performance.In addition,a novel method for routing maintenance and a strategy of loca... |
