| Summary: | 碩士 === 中華大學 === 資訊工程學系(所) === 97 === In recent years with the development and advance of mobile network technologies and the enhancement of computing capability of mobile devices, the applications of mobile devices become more pervasive. Peer to Peer (P2P) networks and Web services are inevitable to be applied to mobile devices. But due to the network bandwidth and computing capability of mobile devices, the applications of mobile P2P and Web services are still limited. In this thesis, we are studying how to apply P2P technology to mobile Web services and investigate how to share Web services in mobile network environment.
Due to the limitation of P2P mobile networks, how to effectively discover and share services is always an important research topic. In this thesis a system is built to expedite service sharing and to fast recognize the services provided by service providers through three system functions: registry, discovering, and sharing. In this system, the record management store (RMS) is used to connect databases. Data can be accessed and exchanged through gateways. Customizing discovery can help match services that meet the requirements of users. Services can be fast shared among user’s mobile devices without agents.
The system is built on JXME which is a JXTA technology on mobile platforms. JXTA is a P2P technology based on service-oriented computing and JXME is suitable for P2P mobile networks. The system is verified through the simulations of single and multiple machines. The functionalities of JXME and relay peer nodes are analyzed in the single machine environment. The performance of system sharing is discussed in the multiple machine environment.
