The Research of Resource Searching Algorithm in Mobile P2P Network

The high dynamic of mobile peer-to-peer network makes the topology of network changing frequently, inconsistent of overlay network and bottom physical network topology, which can make worse network capability, higher failure rate of super-peer, longer query delay, lower effect of data transmission, as well as lower success rate of resource searching and system instability. This paper proposes a resource searching algorithm based on super node, which can select a node with high capability and weak dynamic as super node, and adopt the super node to query quickly. It improves the performance of resource searching and system stability in mobile P2P network. The results of experiment show that the proposed algorithm could reduce the failure rate of index information, shorten the query delay and enhance the success rate of resource searching.
