Using virtualized operating systems as a ubiquitous computing infrastructure

The personalization of computing environments is one of the key aspects of ubiquitous computing, and such personalization requires isolated computing environments for better security and stability. This paper describes our ubiquitous computing infrastructure architecture that is based on virtualized operating systems in order to enable ubiquitous devices and servers to be shared securely and reliably. Our architecture also includes CPU resource management mechanisms to support time sensitive applications and to make the execution of applications stable on shared devices.
