Towards a conceptual model for context-aware adaptive services

Recent advances in both portable devices and wireless networks make mobile computing a reality. Embedded and invisible computing resources are paving the way to a new paradigm known as pervasive computing. More attention needs to be paid to the development of intelligent services in such a highly dynamic environment. This paper aims to present a conceptual model for context awareness based service adaptation methodology. We describe context in context space and represent it with 4-tuple. We then discuss context awareness in terms of both context organization and utilization. Finally, we introduce the notion of adaptation and present the framework for context-aware adaptive services.
