Increasing reliability and availability in smart spaces: A novel architecture for resource and service management

Smart spaces are physical spaces where services provided by Consumer Electronics (CE) devices with varying resource availabilities work together to realize user-specific automated scenarios. These scenarios may be interrupted in case one of the services making up the scenario stops working, e.g. due to lack of resources, node failure or leave. Therefore, the user experience is highly dependent on the availability and reliability of smart space resources and services. This paper proposes an architecture for resource and service management in smart spaces. We present mechanisms for automatic node entry and exit, service discovery and matching, failure detection and recovery, and resource monitoring. The proposed architecture is evaluated in the context of a simple use case scenario.
