With the development of wireless communication technologies and mobile devices, the P2P network technology has the conditions to be used in wireless environments.Resource search is to discover requested object in mobile P2P network (mobile peer-to-peer network), which is one of the core issues of mobile P2P application.Aiming at low efficiency of resource search in mobile P2P network, a search strategy using improved random walk based on node reputation (SSRWBR) is proposed in the paper.By introducing a reputation mechanism based on the random walk model, the neighbor ultrapeer with maximum reputation value is selected to forward the query walker during the search process, which can solve the problem of low resource efficient searching.
