摘要
针对传统Ad Hoc路由协议在动态高速环境下路由效率较低的现状,基于多路径原理提出了一种新型的动态多路径Ad Hoc路由协议(D-AOMDV).该路由协议是对传统Ad Hoc路由协议的多路径扩展,通过计算多条开环、节点或链路不相交路径,充分利用已有的有效路由信息,达到提高路由效率的目的.实验结果表明:动态高速环境下,该路由协议在分组传递率,平均端到端延时,路由发现频率方面均优于传统Ad Hoc路由协议.
There is a lower routing efficiency for Ad Hoc protocol in dynamic speed environment.Based on multi-path routing principle,a new Ad Hoc routing protocol was proposed.It was a multi-path expansion of traditional Ad Hoc routing protocol.Effective routing messages were sufficiently used by utilizing the backup routing messages.The experimental results showed that the new protocol performed better in terms of packet delivery fraction,average delay and routing discovery frequency in dynamic speed environment.
