Application Research For Mobile HP2P Protocol

Along with the Internet technology rapid development,the file sharing service has become one of the most widely used Internet applications.Mobile Internet can be regarded as the combination of mobile communication network and Internet.Especially in recent years,the rapid development of mobile Internet and mobile terminals has greatly changed people's lives.However,with the development of mobile Internet,file sharing service based on Mobile P2P network has not developed rapidly and integrally in the field of Mobile P2P.Considering the change of network topology due to mobile Internet mobility,mobile terminals' limited processing ability and the importance of resource localization algorithm,how to design a protocol architecture and related application for Mobile P2P network is the focus of Mobile P2P research.This thesis mainly designs a protocol architecture which can be used in Mobile P2P network.It is called Mobile HP2P(Hybrid Hierarchical P2P)and combines the advantages of structured and unstructured and centralized P2P network,such as scalability,lower network load and higher stability.At the same time,this thesis also designs the realization of related services,and implements a file sharing application based on the Mobile HP2P.Firstly,the thesis introduces the Mobile P2P network and related knowledge of Android.Secondly,it describes the Mobile HP2P protocol and related system services in detail,such as resource publishing,searching and downloading of mobile node,metadata redundancy and local single-point failure.Then,this thesis gives the system analysis,general design and concrete implementation of this system,whose file sharing application supports the shared files publishing,searching and downloading without server involvement,including data exchange between mobile and PC and mobile and mobile.At last,the function and non-functional tests of the system are shown,making sure the availability of the Mobile P2P file sharing service.
