Abstract. Context-aware systems offer entirely new opportunities for application developers and for end users by gathering context data and adapting systems' behavior accordingly. Especially in combination with mobile devices such mechanisms are of great value and claim to increase usability tremendously. In this paper, we present a layered architectural framework for context-aware systems. Based on our suggested framework for analysis, we introduce various existing context-aware systems focusing on context-aware middleware and frameworks, which ease the development of context-aware applications. We discuss various approaches and analyze important aspects in context-aware computing on the basis of the presented systems.
For example, a survey on context-aware systems REF describes the basic design principles of context-aware architectures and depicts the different context models.
