Recent studies have shown in which extent peerto- peer file sharing traffic occurs in the global Internet. Mobile users want the same type of service, thus supporting them with peer-to-peer applications is naturally the next step. The main goal in the design of proposed architecture was to provide searching for shared files not only among vehicles during opportunistic meetings, but also among all vehicles in the Vehiclular Ad Hoc Networks. In this architecture new roles to access points are attributed. A key point in this plan is to build clusters and choose supernodes. An important criterion for any choice making no doubt is the minimization of message overhead. In this Paper the influence of incorporating vehicles traffic in the organization of access points, add to connection of distant vehicles has been studied. I have built a stable architecture providing support for a high dynamic environment beside conceiving a protocol supporting for this architecture. In addition to traditional services of indexing and searching, strategies for a cost effective car-positions management, synchronization of requests and deliveries have been developed.
