Toward A Generic Infrastructure for Ubiquitous Computing

The recent technological overhangs have focused on the democratization of wireless networks and the miniaturization of communication devices. In this context, Ubiquitous Computing is a recent paradigm whose objective is to allow users to access data, and make information available anywhere and at any time. In other terms, Pervasive Information Systems (PIS) constitute an emerging class of Information Systems where Information Technology is gradually embedded in the physical environment, capable of accommodating user needs and wants when desired. PIS differ from Desktop Information Systems (DIS) in that they encompass a complex, dynamic environment composed of multiple artifacts instead of Personal Computers only, capable of perceiving contextual information instead of simple user input, and supporting mobility instead of stationary services. In this paper, as an initial step, the authors present PIS novel characteristics compared to traditional desktop information systems; the authors explore this domain by offering a list of challenges and concepts of ubiquitous computing that form the core elements of a pervasive environment. As a result of this work, a generic architecture for intelligent environment has been created. Based on various and related works concerning models and designs. This framework can be used to design any PIS instance.
