Searching Mechanism in the Mobile Peer-to-Peer (P2P) Network

摘要

With the increasing diversity and quantity of mobile terminals, the demand for new applications in the mobile networks has become increasingly high in entertainment, education and commerce. However, due to the limitations of mobile devices, such as energy, bandwidth, 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. Our objective is to emphasize both scalability and reliability issues of searching mechanism in the proposed mobile P2P network in a cost effective way. In this system, an index server is connected to a GGSN in each PLMN to provide the sharing resource index information. We have evaluated the index server searching mechanism in the proposed system comparing with the general flooding searching mechanism, and the results show that our design significantly improves the energy cost and the system scalability, and to some extent, it compensates the deficiency of mobile terminals.
