P2P Services Design And Implementation Based On WiFi Smartphones

With the process of infomationization and application of network technology , network inside enterprises is gradually improved. The computer network has become the main carrier of information acquisition and storage, and integrated with work procedure closely in order to provide a convenient and efficient way for information communication during work and life. P2P (Peer To Peer) develops rapidly as a new network technology to provide a very convenient way for sharing resources, making it has been accounted for 60% ~ 80% in Internet business currently.As the main mobile phone operating system, Symbian OS is widely used. Along with mobile communications flourishring over these years, Series 60 as one of the mobile phone platforms in Symbian OS developed many applications, the software developments in it have become growth hotspot. The mobile versions of Java and C++ provide rich development environments for creating new customer applications and business applications.This paper investigated P2P file-sharing system based on the Series 60 platform, and analyzed the structure of components and the core protocols in JXTA standard to design the XML signals with JXTA standard and transmit datas with Sockets in Symbian environment. Besides, through WiFi in accordance with the JXTA protocol standards to exchange informations, this paper simulated the P2P files sharing and transfering process in the office environment with several Series 60 terminals holders, so they could obtain useful information conveniently.
