The resource search algorithm based on peer's dynamic performance in mobile peer-to-peer network

In mobile peer-to-peer network, peers' dynamic character is strongly and highly. It makes the network searching performance worsen, resulting in lower success rate of resource search and system instability. The proposed algorithm, that is the resource search algorithm based on peer's dynamic performance (RSBDP), can select peers with high performance as super-peer, and adopting the scheme of redundancy super-peer for search. It improves the network search performance and enhances the stability of the system in mobile peer-to-peer network. The experimental results show that the proposed algorithm can reduce the failure rate of index information, shorten the query delay and enhance the success rate of resource search.
