Abstract:
Dynamic adaptive systems are systems that change their behavior according to the needs of the user at run time. Since it is not feasible to develop these systems from scratch every time, a component model enabling dynamic adaptive systems is called for. Moreover, an infrastructure is required that is capable of wiring dynamic adaptive systems from a set of components in order to provide a dynamic and adaptive behavior to the user. To ensure a wanted, emergent behavior of the overall system, the components need to be wired according to the rules an application architecture defines. In this paper, we present the Dynamic Adaptive System Infrastructure (DAiSI). It provides a component model and configuration mechanism for dynamic adaptive systems. To address the issue of application architecture conform system configuration, we introduce interface roles that allow the consideration of component behavior during the composition of an application. Moreover, we extend the interface roles and application specifications by a quality of service concept. This enables a component to not only require a syntactical and semantical correct wiring, but also to demand the – from its viewpoint – best service.
