In this paper, we introduce a service framework using the VPW (Virtual Personal World) and its associated service conflict resolution algorithm based on the VPW. In this new service model, users can manage their own spaces that include all things to support their services. Previous service frameworks are focused on designing adaptive software applications by using heterogeneous devices and softwares. However, these service frameworks have some problems to provide adaptive services to the users. To resolve the limitation that is caused by multi-user environment, we propose a service conflict resolution algorithm. Therefore, our proposed service framework based on the VPW can support more user-centric services, reduce the number of service conflicts, and improve the number of conflict resolutions. The experiment result shows that almost 40% resolution rate can be achieved comparing with the location based system and 30% work time can be improved comparing with the location based system.
