A User-centric Applications Sharing Model on Pervasive Computing

Pervasive computing is booming research field, in which innovative techniques and applications are continuously forming to provide users with high quality ambient and personalized services. Applications available for end-users have become increasingly abundant, distributed and heterogeneous in pervasive computing environment. How to share and utilize these applications is a significant research problem in pervasive computing environment. This paper puts forward a User-centric Applications Sharing Model (U-ASM). The U-ASM mainly focuses on abstracting the applications from service providers and end-users, and then utilizes virtualization technology to encapsulate applications and uses ontology organize distributed applications as a logic unit with semantic relationships so that it can provide better quality of service for end-users. The research result has been applied in R&D Infrastructure and Facility Development of Ministry of Science and Technology and has great flexibility and extensibility.
