摘要 利用方向性天线的高空间复用度和高传输能力,提出了一种基于位置信息的车联网路由恢复方法。为了减少路由修复过程中因目标节点移动对路由修复造成的影响,方法利用GSP定位装置提供的行车参数信息,对路由修复过程中目标节点的移动轨迹进行了预测并对目标节点位置进行修正。仿真实验表明:方法有效提高了路由修复成功率、降低了路由修复延迟和路由修复开销。 By using the high spatial reuse and high transmission ability of directional antennas, an algorithm of routing recovery for vehicular ad hoc networks based on location information is proposed in this paper. In order to reduce the side effects of mobility of vehicles, this algorithm uses the position information acquired by GPS devices during rout- ing recovering, predicts the traces of vehicles and modifies the location of vehicles. The simulation shows that using this algorithm the successful rate of routing recovery is improved, and the lag and the cost of routing recovery is reduced.
