Abstract

With the rapid development of wireless communication technologies and mobile devices, the mobile peer to peer (MP2P) network has been emerged. Since the computation ability, bandwidth, storage and the dynamic network topology of mobile devices are limited, directly applying the existing wired P2P method to wireless ad hoc network will result in poor performance. A hierarchical MP2P architecture based on super peers has been proposed to alleviate the problem. However, the management cost of the mobile network topology is still high. In this paper, we propose a hierarchical MP2P architecture using clustering mobile peers. The proposed architecture considers the maximum connection time of connected peers, the hop count with the super peer, and the number of connected peers of the super peer. The connection time between the connected peers can be determined by the location, velocity and communication range of each mobile peer. Therefore, the network topology is relatively stable, the management cost of the network topology is decreased and the success rate of contents search is increased. Experiments have shown that our proposed scheme outperforms the existing schemes.
