High-performance complex event processing for large-scale RFID applications

RFID technology holds the promise of real-time identifying, locating and monitoring physical objects. Complex event processing is the key part of the RFID middleware. Most of the current methods of complex event processing can´t support large-scale RFID applications since they have not considered much on performance and distributed data. In this paper, a distributed CEP architecture is proposed which spreads centralized CEP tasks load over multiple communicating stations over CORBA. Based on this architecture, a high performance plan based distributed CEP method is proposed which uses parallel operations to improve performance. The experimental study shows that the performance of our approach is remarkable in large-scale RFID applications.
