A context-aware publish-subscribe middleware for distributed smart environments

We present and discuss a context aware publish subscribe system. This allows for efficient communication between different components within distributed environments. For this we introduce context-awareness into the subscription handling. Our middleware allows to attach context properties to event subscriptions. Only if those properties are satisfied by the current state of the world, the events are distributed within the system, which minimises the communication. Finally we discuss a larger use-case for our system.
