Adaptation des services sensibles au contexte selon une approche intentionnelle

Abstract : The emergence of new technologies has changed the use of these technologies in order to access to the various systems that take place in our daily life anywhere and anytime. Indeed, the democratization of devices and the evolution of mobile technologies have changed the way these systems are used in a pervasive environment. As part of the company, these new technologies have expanded the boundaries of Information Systems (IS) beyond the physical boundaries of the organization. Chiefs Information Officers (CIOs) are confronted with new modes of interaction with their SI. Information Systems are thus faced with an environment for which they were not specifically designed. These systems must now face a pervasive environment, and in the future, integrate physical as well as logical and organizational elements. We are now witnessing the emergence of a new generation of Information Systems: " Pervasive Information Systems" (PIS). The Pervasive Information Systems want an answer to this important evolution of SI. Against, they must manage the heterogeneity and dynamism of the environment in a transparent manner to best meet the users needs. Thus, currently we are facing a problem of design and implementation of PIS that meets all the needs of transparency, adaptation to the environment and adaptation to the user. Although, PIS represent today a new generation of SI that is difficult to conceptualize, with few methods and models available. Thus, it becomes essential to establish a more formal framework to help designers better understand PIS and especially to the better control of it, while ensuring the necessary transparency to these systems. In this thesis, we propose a new intentional and contextual vision of PIS. This new vision represents a user centric vision of PIS, which is transparent, non-intrusive and understandable to the user. It is based on service orientation, context-awareness and intentional approach to solve the problems of transparency, adaptation to the environment and adaptation to users. Subsequently, we propose a more comprehensive solution to achieve this intentional and contextual vision of PIS. We propose a conceptual framework for describing and formalizing PIS and all its elements to help CIOs in their system design. We then propose mechanisms for services discovery and prediction that are integrated in the architecture of PIS manager. Finally, we propose a methodological approach for the design and the implementation of PIS that supports the transition between the conceptual framework to its implementation with the proposed architecture.
