Design of Virtual Personal Computing Environment for Ubiquitous Computing

This paper presents a ubiquitous computing technology called Virtual Personal Computing Environment (VPCE), which enables users to access their personalized computing environments anywhere using any available terminals. The key feature of the VPCE is that it can be constructed dynamically by reassembling application services and resources distributed over networks, which is different from the traditional desktop personal computing environment that is tied to an individual computer to execute. In VPCE, users work with a heterogeneous collection of application services, and data access by application as well as the application accessed by users are distributed over networks, while the applications and data distribution is transparent to the users.
