摘　　要：针对移动自组网路由协议在用于车联网时路由恢复延迟长、效果差的问题,提出了一种独立于具体路由协议的路由恢复方法。主要用于高速公路无基站情况下车与车之间的通信。能在通信路径断开后快速恢复并保证恢复后的通信路径有较高的可靠性。仿真实验表明,算法有效地降低了路由恢复延迟和开销,提高了路由修复成功率和路径生存时间。When using vehicle ad hoc networks,mobile ad-hoc network routing protocols exhibit long delay and low effect in route recovery.Aiming at this problem,a route recovery method independent of any specific routing protocol is proposed,which is mainly used for the vehicle to vehicle communication in situation of the highway without base station.This method can restore quickly when the communication path is disconnected and guarantees a higher relia bility communication path after the recovery.The simulation experiments show that this method not only can effectively reduce the route recovery delay and overhead,but also increases the route recovery success rate and lengthen the path＇s lifetime.
