A novel framework of context-aware system based on space mapping

As ubiquitous computing envi ronments grow faster, more and more context-aware systems ar e developed for them. For these systems, the modeling and reasoning of context is very important. This paper first proposes a concept of space mapping and then based on this concept, a simple but practical framework for context-aware system is proposed. Finally, analyses of this framework prove its advantages in efficiency, scalability and flexibility.
