由于军事和抢险救灾等方面的需要,移动Ad Hoc网络路由协议成为当前研究的热点之一。而目前能动态适应网络拓扑变化的路由协议较少。针对这一情况,在AODV协议的基础上,提出了一种自适应多径路由协议AODV_AM,采用备份路由机制并以链路稳定性为选路标准,动态适应网络拓扑的变化。通过仿真证明,该协议在分组传输率、时延和路由开销方面性能得到了较大的改善。
Due to the needs of military and disaster relief, mobile Ad Hoc network routing protocol has become one of the hot spots in current research. At present, there are few routing protocols that can dynamically adapt to changes in the network topology. In response to this situation, based on the AODV protocol, an adaptive multi-path routing protocol AODV_AM is proposed, which adopts the backup routing mechanism and uses the link stability as the routing standard to dynamically adapt to the change of the network topology. The simulation results show that this protocol has greatly improved the performance of packet transmission rate, delay and routing overhead.
