BKCAS: A distributed context-aware pervasive information system to support user roaming

Abstract

Over the last few years, Pervasive Computing has become a very active research topic in both academia and industry. In spite of its undeniable benefit, 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 BKCAS (BK Context-Aware System), a novel architecture for scalable pervasive information system having the capability of intelligently routing multimedia messages to users based on 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 minimized deployment cost and improve user acceptance. Furthermore, we successfully prototype the system and evaluate its performance by an automated testbed. © ICITA 2009.
