The study of RFID system based on CEP

With the rapid development of RFID technology, the demands of a relevant software system have been rising in recent years. Complex Event Processing (CEP) is a technique for analyzing streams of event data in real-time. Because the raw RFID data is unreliable, CEP can play a critical role in RFID system. In this paper we propose a high performance complex event detection algorithm of performing CEP directly over unreliable RFID event streams by incorporating cleansing requirements into complex event specifications.
