Recently, Mobile Ad Hoc Networks is a hot researching area of computer network technology at home and abroad, routing protocol is one of the core technologies in it. In Mobile Ad Hoc Networks, in order to improve the performance of routing protocols, many domestic and foreign scholars have already begin to study the routing technology based on the location services protocol. Through analysis of the existing Mobile Ad Hoc network routing technology, this paper proposes a new routing protocol called TGPSR which is based on XYLS. In addition, we analysis and design the application of TGPSR in Vehicular Ad Hoc Networks.XYLS-based TGPSR routing technology take two-hop greedy strategy to send data packets, which efficiently improves the performance and success rate of greedy strategy ,by making full use of location information provided by location services protocol. In the TGPSR, when a packet reaches a region where greedy forwarding is impossible, the algorithm recovers by routing around the perimeter of the region.
