Abstract: This paper takes some analysis on inter-vehicle oriented mobile ad hoc network communication in metropolitan area, making the routing research into real world. It documents vehicle motion behavior and concludes rule of vehicle movement. Basd on this motion rule, it proposes an improved ad hoc routing protocol and a network architecture adapted to the protocol. At the end , it valuates performance of the improved network, utilizing real-world vehicle movement data.
