Une nouvelle approche de modélisation et d'adaptation contextuelle des systèmes pervasifs : la plateforme COALA (COntext Adaptation Platform)

Abstract : The study of the literature proves that context-awareness has become a key element for the implementationof adaptive services in pervasive interactive applications. In fact, the present work focuseson the context of modeling issues for the adaptation of services provided by the invective pervasiveapplications to the sensitivity of context situations. The context is no longer a pre-established and predefinedtemplate when designing interactive applications systems but rather a dynamic description ofthe common situations that can be discovered in the context data and can dynamically be changedwhen changing user’s requirements and preferences. The systems of pervasive applications must beavailable in different contexts of use according to the user’s environment, the terminal being used, location. . .. The major challenge of these systems accordingly relates to the adaptation of the servicesoffered by interactive applications to the user context. In Order to respond to different requirementsof dynamic adaptation to changes in contextual situations, following the changes in usage patternsas well as the dynamics of the pervasive environment and the heterogeneity of context data sources,we propose mechanisms used to provide the traceability of the context as Virtual contextual Cards(VCOC). These works were carried out and applied as part a PhD under joint supervision betweenTunisia and France.
