摘要
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。
Because of the necessary of such as military affairs and disaster rescuing, routing protocols for. mobile Ad Hoc networks become one of hotspots of research. While a few routing protocols can adapt to the change of network topology dynamically.According to this situation,A adaptive mutipath routing protocol is proposed based on AODV,which makes use of backup routing mechanism .Its standard of selecting route is link stability and it can adapt to the change of network topology dynamically. The performance via simulations shows that it is improved in packet delivery ratio, average delay and routing cost.
