Supporting Smart Space Infrastructures: A Dynamic Context-Model Composition Framework

Smart spaces are environments where intelligent devices can provide end-users with personalized and context-aware services. The biggest barriers against effective realization of smart spaces are the lack of interoperability between different ubiquitous computing infrastructures and standardized way of service operations. From this perspective, we present a framework for smart space interaction supporting interoperability and based on ongoing standardization efforts. The framework supports dynamic composition of context models based on multi-device and service interactions taking into account security and privacy issues. We show how we align ongoing W3C standardization efforts with key elements of the framework such as composition models and state-based mart space application development approaches. We conclude by providing our thoughts and plans about future extensions and interoperability needed between specifications for effective smart space realizations.
