Pervasive Information Systems Adaptation Challenges

Abstract

Initially, a significant number of contextual information can be employed to describe the pervasive system. Hence, to design this type of system, there is a stern need for a new information system. Unlike the classical information system, the new system integrates the mobile devices characterized by different hardware and software capacity and other useful devices. Therefore, most pervasive information system designers provide mechanisms and architectures to effectively save, recover and submit the most relevant information to the user regardless of location, time and the user's equipment which are independent of the network constraints. In this paper, the authors present a model to describe the pervasive information system through the use of the existing contextual models. In the same context, they suggest a semantic description to adapt the users to six categories of contextual information by taking the semantic-web-service creation as a basis. Finally, they present the semantic rules applied to the intended description and notification system to validate these rules.
