An adaptive architecture for context-aware interaction in pervasive applications

Adaptation is one of the key challenges in pervasive computing. Context-aware applications need to respond to dynamic physical and computing environments. In this paper, we propose an adaptive architecture for context-aware pervasive systems. The basis of our approach is that entities (e.g., user, device, application or group) are modelled as self-managed composites. Each composite maintains a representation of its relationships with other entities and any context conditions that affect those interactions. It then uses this context model to monitor and control its interactions. This loosely coupled architecture allows flexibility in configuring and monitoring components of pervasive systems, and thereby helps the systems to be more adaptable.
