In mobile p2p network, peers have strong dynamic character and mobility. It makes the topology of network change frequently and the network performance worsen, and also cause high failure rate of peers and instability of system. This paper proposed a super-peer selection algorithm based on AHP for mobile p2p network. It takes the performance of bandwidth, CPU, storage, on-life time and mobility into account, and adopts AHP to select the most suitable peer in the partitioned region of network as super-peer. It effectively improves network performance and system stability in mobile p2p network. The experimental results show that the proposed algorithm can reduce the index information failure rate, the average search path length and super-peer failure rate, shorten the query delay.
