A new mobile peer-to-peer architecture

With the increasing diversity and quantity of mobile terminals, the demand of new applications in the mobile networks has become increasingly high. However, due to the limitations of mobile devices, such as bandwidth, storage, and computation capability, and unpredictable connectivity, the development of new applications is restricted. In order to address this problem, we present a new scalable and reliable mobile P2P network architecture which is composed of cellular Ad Hoc network, wireless access network and 3G core network. Our objective is to emphasize both scalability and reliability issues of searching sharing resource index information in a cost effective way. In this system, an index server is connected with a GGSN in each PLMN to provide the sharing resource index information. We have evaluated the proposed system by comparing the index server searching mechanism with the general flooding searching mechanism. The results show that our design significantly improves the energy cost and the system scalability.
