Until, recently, the wide deployment of pervasive information system is still limited due to high cost of infrastructure, and more important, its requirement of rebuilding a new information infrastructure from scratch without reusing much from the current working system. In this study, we propose Bkhoa context-aware system (BKCAS), a novel architecture for scalable pervasive information system having the capability of intelligently routing multimedia messages to users based on the context processing. Moreover, BKCAS support user roaming over a large number of loosely coupled autonomous domains. Differ from many other pervasive systems, which assume a completely newly built infrastructure, our approach focuses on reusing the most of current infrastructure, and incrementally extend the system the most non-intrusive way in order to minimised deployment cost and to improve the user acceptance. Furthermore, we successfully prototype the system and evaluate its performance by an automated testbed.
