Abstract: With the development of RFID technology,RFID is being applied ubiquitously in every field. With throughly processing and analyzing RFID data,more complex events and implicit knowledge could be discovered to effectively support advanced applications such as event monitoring and pre-warning. Due to the speciality of RFID,it is insufficient to take use of the state of art active database and data stream techniques for high-performance RFID event detection and processing. The paper analyzes the characteristics of RFID data,makes a survey of the newest technology over RFID complex event processing,and explores the new problems to be solved urgently,including RFID data cleaning,data-centric event detection techniques,event-centric event detection techniques and complex event processing systems,and finally gives an outlook of the research issues in the future.

Key words: RFID technology, data cleaning, complex event processing, data stream technology
