Research Of File Sharing Systems Of Mobile P2P Based On JXME Platform

With the development of P2P technology, its applications in Internet demonstrate more superiority and importance. It is a distributed network model which doesn't rely on servers, with good usability, robustness, scalability and fault tolerance. The mobile communication services can get inspiration from the successful application of P2P technology in Internet. And it will be applied to mobile phone networks, to provide users with resource-sharing and other services.The purpose of this paper is that P2P will be applied to file sharing in mobile network. It will change the C/S transmission mode used by traditional mobile network, and use the more cutting-edge technology: JXME. And it enable mobile phones and other mobile devices to transmit and share using P2P mode.Firstly this paper analyzes the situation of P2P in fixed network, and leads to the development, trends, existing problems and est. Then it introduces JXME which implements the JXTA, special for the J2ME platform for wireless resource constrained devices. And it provide resource-constrained wireless devices with the ability which can join the P2P network, use the resource in Internet and interact with other peers. Thirdly, the paper analyses its shortcomings on security issues and puts forward a security trust model for mobile P2P. Finally, it gives the architecture program of the system, the implementation process and test analysis.The main innovation in this paper is:Learned from P2P technology and experience in fixed network, it puts forward a hybrid P2P structure applied to mobile P2P network and realizes resource-sharing among the P2P nodes based on JXME platform.This paper puts forward a trust model based on reputation applied to mobile P2P which can promote nodes' cooperation, stimulate nodes to share resources and effectively reduces the computational complexity. It can solve the security trust issue of low-end devices in mobile P2P network.
