Distributed hierarchical complex event processing for RFID stream
Shenghong Yang · Computer Engineering and Applications Journal · 2010
The current methods of Complex Event Processing(CEP) in RFID application usually focus on centralized architecture,which can't support distributed RFID application.The centralized CEP also lacks of robustness and scalability because of single point failure or network break.On the other hand,hierarchical complex event is not supported well in many efficient complex event detection methods for RFID.Distributed hierarchical complex event detection architecture is proposed which is based on CORBA(Common Object Request Broker Architecture).A high performance plan based distributed hierarchical complex event detection method is proposed which uses parallel method to improve performance.The experimental study shows that the performance of this approach is remarkable in large-scale distributed RFID applications.
