The Architecture on the Mobile P2P System and the Study for the Key Technology

The architecture on the mobile peer-to-peer(P2P) system which is composed of cellular Ad hoc network and 3G core network is proposed.The construction solution and the functional architecture of each network entity are described in detail,and at the same time,the communication processes between peers are analyzed. A simple and efficient index server searching mechanism is presented in the constructed mobile P2P system.Simulation shows that,compared with flooding searching mechanism,the energy consumption in mobile P2P system will be improved when in use of index(server) searching mechanism,to some extent,the deficiency of mobile termination is remedied.
