RFID Complex Event Processing for RTLS

Recently, researchers adopt the event-centric methods to process RFID data. To identify RFID complex event in real-time locating system, we propose a new RFID complex event processing method. We analyze the model over data streams based on the timing diagram, and propose a novel technique that infers the relationship between objects and locations, as well as the relationship between objects and objects. Experiments prove the proposed event drove approach can effectively process complex RFID events, and significantly reduces the cost of RFID complex events processing.
