A location and interest based peer to peer virtual navigation system

The increasingly amount of virtual scenes and multimedia data have been the major problems in developing a virtual navigation system. Designers of virtual navigation system need to consider whether the massive data would influence the smoothness of navigation to users, and whether the efficiency of server would be decreased sharply when multiple users are online at the same time. In order to solve this problem, most of existing systems increase the number of servers or the network bandwidth, but the construction cost is also increased as a result. This paper designed a peer to peer (P2P) virtual navigation system with positioning function, this system is based on location and interest of users, so that when users carry mobile equipments such as notebook computer, UMPC, Mini notebook,...etc., walking around the actual scenes of indoor and outdoor areas of campus, users can peer-to-peer download/share virtual scenes and multimedia data from surrounding users or the users have the same navigation interest. Therefore, the transmission efficiency of navigation system would be improved obviously.
