Recently, the increasing use of mobile technologies leads to face with new challenges in order to satisfy users. New systems deal with three main characteristics: context changes, mobility and limited resources of such devices. In this article we try to address such requirements using QoS-driven dynamic adaptations of application deployment. We are(More)
In this article, we address the recurrent problem of QoS management in pervasive computing due to resource limits, context changes and users' requirements. We propose a QoS-driven design process allowing managing applications limits and particularities of mobile devices in order to react to context evolution with dynamic reconfiguration reflecting quality(More)
The recent apparition of mobile wireless sensor aware to their physical environment and able to process information must allow proposing applications able to take into account their physical context and to react according to the changes of the environment. It suppose to design applications integrating both software and hardware components able to(More)
—Resource-constrained embedded and mobile devices are becoming increasingly common. Since few years, some mobile and ubiquitous devices such as wireless sensor, able to be aware of their physical environment, appeared. Such devices enable proposing applications which adapt to user's need according the context evolution. It implies the collaboration of(More)
Design-driven software development approaches have long been praised for their many benefits on the development process and the resulting software system. This paper discusses a step towards assessing these benefits by proposing an experimental study that involves a design-driven, tool-based development approach. This study raises various questions(More)
Recently, the increasing use of mobile technologies leads to face to new challenges in order to satisfy people using mobile devices. As they use their favorite applications on their personal computer at home, people wants to use it on their smartphone or tablet and wants applications to be improved according to GPS position, weather or any contextual(More)
We are currently facing with an important evolution in communication area. People use more and more some mobile and tiny devices to interact with their favourite services. However, these devices have resource constraints which are necessary to be aware in order to offer effective applications in terms of quality and lifetime. In this article we propose a(More)
Since few years, several applications are proposed on mobile devices. However, these applications are not aware of their physical environment. The emergence of wireless sensors, able to monitor their close environment, can provide this service to such applications. This implies an exchange of information between sensors and software components, but they do(More)
