A Mobile P2P Community System

The distributed architecture of vitual community based on P2P has proved to resolves some problems from central architecture such as single point failure. In this paper, drawing on the idea of SOA, we propose an optimized architecture of distributed mobile P2P community system, in which the virtual communities are divided into separately service components which can be deployed in the overlay networks as resource instead of a central server. And the introduction of the physical network aware technique of P4P can help the client find the most suitable service replica. We also propose a replica consistent control mechanism to facilitate the practice of the system in this paper. At last we develope a prototype system of mobile community.
