ReCEC: Resolving Conflicts of Environmental Constraints among Multiple Applications in a Smart Space

As applications deployed in a smart space share the same physical environment, they may interfere (or even conflict) with one another. To guarantee the performance and user experience of the entire smart space, mechanisms for handling such interferes (or conflicts) have to be introduced. We believe that conflicts among multiple applications are caused by their different requirements and impacts on the shared environment, and we model the conflict resolution problem as a Constraint Satisfaction Problem(CSP). We further propose a framework for managing and coordinating context-aware applications in a smart space, and provide an effective and efficient strategy to solve the corresponding CSP. Exhausted simulations are carried out to show the effectiveness of the proposed resolution strategy.
