Ambiant computing takes many various devices integrated to the object of everyday life. Those devices can collaborate to build dynamically new applications. Those applications adapt according to available devices in their execution context. The purpose of this thesis is to propose an original approach to the development of computer applications...

Pervasive devices are becoming popular and smaller. Those mobile systems should be able to adapt to changing requirements and execution environments. But it requires the ability to reconfigure deployed codes, which is considerably simplified if applications are component-oriented rather than monolithic blocks of codes. So, we propose a...

This paper presents Wcomp which is a framework for rapid application prototyping. This framework has been developed for targeting wearable computing applications but can also be used in the field of pervasive and contextaware computing. In the first part of the paper, we investigate the possibility of taking into consideration the relations...

Because of the growing diversity of mobile computer terminals and communicating objects, we observe the emergence of applications using the notion of context. Firstly, we propose an analysis of definitions of context. Then, we present a model in which we simplify the expression of the problems caused by the interaction between the computer, the...

Due to more and more mobile computers moving among smart and communicating devices in our everyday life, we observe the emergence of new constraints in software design. Indeed, device heterogeneity, dynamic software variation, and frequent mobile device apparition/disappearance make software applications compulsorily adapt to their context. In...

After a survey of the specific features of ubiquitous computing applications and corresponding middleware requirements, we list the various paradigms used in the main middlewares for ubiquitous computing in the literature. We underline the lack of works introducing the use of the concept of Aspects in middleware dedicated to ubiquitous...
