Towards model driven design of service-based context-aware applications

ABSTRACT

Context-aware adaptation is an important feature for pervasive computing applications. In our approach, we intend to support the viewpoint of context-aware adaptation as a crosscutting concern with respect to the core "business logic" of an application. In this way, the design of the application core can be decoupled from the design of the adaptation logic. This facilitate the plugging of different adaptation strategies within the same basic application, tailoring it for different contexts. To this end, we leverage ideas from the domains of model-driven development and aspect-oriented design. We assume that the applications to be adapted are designed according to the service-oriented paradigm. Hence, our adaptation mechanisms only assume the knowledge of information accessible in this kind of applications.
