Towards Context-Oriented Self-Adaptation in Resource-Constrained Cyberphysical Systems

We present a context-oriented approach to design and implement self-adaptive component-based software in resource-constrained Cyber physical Systems (CPSs). Because of unpredictable environment dynamics, developers must design and implement CPS software to dynamically adapt to widely different situations. Our approach provides design concepts and language support to meet this requirement against severe resource constraints. To this end, we bring a notion of context-oriented design and programming down to platforms that-because of extreme resource constraints-currently leverage fairly undisciplined design techniques and rather rudimentary component-based frameworks. Early results demonstrate that our approach improves the quality of the resulting implementations facilitating testing, maintenance, and evolution at the price of a negligible system overhead.
