Adaptation au contexte par tissage d'aspects d'assemblage de composants déclenchés par des conditions contextuelles

Due to the multiplicity of mobile computer terminals and communicating objects in our daily life, we observe the emergence of applications using the notion of context. We propose a survey on mobile and ambient computing and then present a model for solving the problem of the interaction between the computer, the user and their environment. We propose a set of definitions of that notion. This is a unified and formal model that allows us to describe rigorously the notion of neighborhood. The latter corresponds to the validation of conditions on a context, which leads to modifications and adaptations of the application. Hence, after another survey on contextual software adaptation, we propose a software adaptation based on aspects of assemblies and dynamic composition of components.
