Discussion on Pervasive Computing Paradigm

Pervasive/ubiquitous computing is considered as the next generation of computing and IT technology (Amor, 2001; Saha et al., 2003). As such an important computing technology, what its computing paradigm should be? For the present network computing, its computing paradigms such as client-server, message passing and the recent peer-to-peer are well known. Are the network computing paradigms suitable and sufficient to the "anytime, anywhere and any format, human-centered" pervasive computing? This paper will analyzed the existing computing paradigms of the present and past generation of computing technologies. Based on the analysis and the unique feature of pervasive computing, a new computing paradigm, master- server paradigm is proposed. In terms of the new paradigm, a pervasive computing based multimodal tele-home healthcare system is designed.
