Abstract: A cloud computing system, UbiCloud, was developed to enable the ubiquitous terminals access to powerful and reliable computing resources anywhere and anytime through building a virtual computing environment between the front end ubiquitous terminals and the back-end servers (cloud). The experiment results show that the system performance is good enough to support most applications deployment on resource-poor terminals.
