Research And Realization Of Organizational Mechanisms For The Virtual Terminal Systems In Ubiquitous Environment

In ubiquitous network environments,there are a variety of wireless technologies and many kinds of terminal equipments. At the same time, user demands for real-time and broadband service of high-performance are constantly increasing, but a single device is unable to meet this.In this case,it has great value to organize multiple terminals working together to provide high quality and broadband service.Based on the situation above,this article researches on the organization of VTS(Virtual Terminals System) with multiple terminals around users to provide service of high-performance.Firstly,a lot of research on the organizational mechanism of VTS is carried out. Organizational mechanism is studied from two aspects:one is about the basic organizational characteristics,and the other is about service-related organizational characteristics.In study of the basic organizational characteristics, P2P is chosen to build fundamental network of VTS after full consideration and analysis of distributed properties of VTS and P2P technology.And JXTA protocols is adopted to validate it;In study of service-related organizational characteristics,the process for deploying VTS with streaming media in mobile network is studied. From a practical point of view, Scheduling algorithm is used to optimize the equalization effect of MLPPP that aims to trunk multi-links.Then the VTS is validated on the basis of study above.In this artice,streaming media in mobile network uses VTS to improve user experience. In actual environment,VTS is build with multiple wireless modems and accessed into internet through RAS(remote access service).At the sending end,streaming media data is segmentalized according to the load of the network.,and data flows reach destination terminals through different networks.The receiver reassembles fragments into the original streaming media and presents friendly contents to the user.In the end, purpose for concurrent transfers of streaming media is achieved. By comparing quality of streaming media service before and after using VTS, this article verifies that the VTS has the ability to effectively use multiple terminal capabilities to improve the user experience.
