8th IEEE Workshop on Context Modeling and Reasoning Decoupling Context-aware Services

Abstract—We present a novel software architecture for contextaware applications based on a distributed, non-monolithic, simple and extensible relational model for representing context; a service-oriented architecture for computing these relations in a decoupled, flexible fashion; and with data driven, event based communication providing the kind of fine grained dynamic service composition required in mobile and volatile environments. A prototype implementation is running a Bluetooth–sensor-based active map of users at our home university. I
