Keywords: mobile peer-to-peer, super-peer, dynamic performance, index information,query delay. In mobile peer-to-peer network, peers have strong mobility and the topology of network change frequently. It can make the network performance worsen, also cause high failure rate of super-peer and instability of the system. The proposed algorithm, that is the algorithm of super-peer selection based on dynamic performance in mobile peer-to-peer network, can select peers with high dynamic performance as super-peer, and adopt an alternative of backup super-peer. The experimental results show that the proposed algorithm could lower the failure rate of index information, shorten the query delay and reduce the failure rate of super-peer: introduction.
