摘　　要：文章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(Vehicular Ad Hoc Networks,VANETs)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,该方法利用全球定位系统(Global Positioning System,GPS)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,该方法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 the aid of the high spatial reusability and high transmission ability of directional antennas, an algorithm of routing recovery based on location information in vehicular ad hoc networks （VANETs） is proposed. In order to alleviate side effects of the mobility of vehicles, this algorithm predicts the traces of vehicles and modifies the locations of vehicles by using position information ac- quired by global positioning system（GPS） devices during routing recovering. The simulation result shows that the success rate of routing recovery is improved by this algorithm. The lag and the cost of routing recovery is also reduced by this algorithm.
