Abstract: Aiming at the problems that peers have a strong ability of moving and the topology of network changes frequently in the mobile Peer-to-Peer(P2P) network, which make low efficiency and fallibility of the system, this paper proposes an algorithm of super-peer selection in mobile P2P network, it selects a peer with more powerful and longer lifetime as a super-peer, and uses the technique of backup super-peer, which can improve the efficiency of a system in the mobile P2P network system. Experimental results show that the algorithm can reduce the failure rate of super-peer and shorten the query delay.
