摘　　要：如果目的节点的位置信息较准确,GPSR路由协议可以高效地发送数据包到目的节点。目的节点的位置信息不准确时,则会导致数据包的严重丢失。针对这个问题,提出了TGPSR(Two-hop Greedy Perimeter Stateless Routing)路由协议:每个节点维持两跳的邻居节点列表,显著增加了对目的节点位置信息的容忍度,在位置信息不够准确的情况下也可以把数据包发送到目的节点。基于XYLS(Column-Ron-Location Service)的TGPSR协议利用XYLS位置服务协议负载较小、可扩展性良好的特点将更多的带宽用于数据传输,进一步提高协议的性能。If the location information of destination node is more precise,GPSR can be effectively sent data packets to the destination node.Conversely,it will lead to serious packet loss.To solve this problem,a new routing protocol called TGPSR（Twohop Greedy Perimeter Stateless Routing） is proposed.In TGPSR routing protocol,each node maintains two-hop neighbor node list, which improves the tolerance of location information of the destination node and makes sure that the data packets can send to destination node by inaccurate location information.The TGPSR route protocol,based on XYLS（Column-Ron-Location Service）,will further improve performance of protocol,by taking advantage of smaller load and good scalability features of XYLS to make more bandwidth to be used to data delivery.
