With fast development of mobile telecommunication, the band of mobile network is becoming wider and wider and the mobile termination's processing ability is getting stronger and stronger. P2P technology which is used widely in Internet will extend to mobile equipment and be used more widely. It has significant meaning of using P2P in mobile environment for operation business and users. Mobile Peer-to-Peer Network (MP2P) has the following characteristics, such as continuously changed network structure, source-limited nodes, network address mismatch with identification mechanism and so on. All these characteristics make using P2P have to solve a serial problems such as network structure, resource searching strategy, data dissemination, security and privacy and trusty transmission. Two key problems: resource searching and trusty transmission has been studied.For resource searching, the existing researches have deficiency in flexibility, proportionality, adaptability. A M-Tapestry resource searching model has been designed based on Tapestry from improving existing P2P searching strategy in order to be suitable for MP2P Network perspective.
