Ubiquitous cloud: Managing service resources for adaptive ubiquitous computing

The adaptive ubiquitous services, which dynamically adapt behaviors to requirements and contexts, are one of the major challenges in the ubiquitous computing. To facilitate the management of ubiquitous service resources, this paper presents a novel platform called ubiquitous cloud, borrowing the concept of the cloud computing. The ubiquitous cloud supports various stakeholders to use appropriate ubiquitous objects in infrastructure, platform and application levels. We present an architecture consisting of four key components: the service resource registry, the adaptive resource finder, the context manager and the service concierge. To demonstrate the effectiveness, we develop a practical adaptive service “room environment relocation service” in an actual home network system, with and without the proposed ubiquitous cloud.
