Dynamic composition and adaptation in adapt-medium

International audienceIn the presence of operational context changes, many applications must use dynamic adaptations in order to meet requirements. When an application has a set of distributed objects that collaborates to offer a particular function, adaptations involving simultaneous distributed processes may affect such collaborations, planning distributed adaptations is thus a complex task for developers. This paper presents Adapt-Medium, an architecture of adaptive distributed components. In the architecture, adaptations are realized by performing dynamic compositions of distributed components. We introduce a model-based process for 1) specifying architecture variants of such distributed components and 2) automatically generating adaptation plans that are performed at runtime to switch between architecture variants
