%X Context awareness is a computing paradigm that makes applications responsive and adaptive with their environment. Formal modeling and verification of context-aware systems are challenging issues in the development as they are complex and uncertain. In this paper, we propose an approach to use a formal method Event-B to model and verify such systems. First, we specify a context aware system’s components such as context data entities, context rules, context relations by Event-B notions. In the next step, we use the Rodin platform to verify the system’s desired properties such as safety properties. It aims to benefit from natural representation of context awareness concepts in Event-B and proof obligations generated by refinement mechanism to ensure the correctness of systems. We illustrate the use of our approach on a simple example.
