A New Paradigm of Pervasive Information Systems
Résumé
Due to the revolution of Information Technology, a new computing era is on the way. Many challenges need to be met, especially in a mobile and dynamic environment where users are interacting with different devices and constructing ad hoc networks, while systems are supposed to provide them with proactive and value-added services. An analytical study of pervasive information systems has led us to view them as environments. Our objective, in this article, is to assure the homogeneity and the interactivity between the sub components of these environments and to highlight the importance of quality assurance and multilayered adaptation in the conception process of pervasive systems in order to avoid trade-offs.
