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.

摘要： 随着RFID技术的发展,RFID应用正无所不在。通过对RFID数据的深入处理和分析,可以发现更复杂的复合事件和隐含知识,从而有效地支持事件监控、事件预警等先进应用。由于RFID的特殊性,依靠现有的主动数据库技术和数据流管理技术难以实现高效的RFID事件检测和处理。分析了RFID数据的特点,归纳和总结了RFID复杂事件处理的最新技术,讨论了一些亟待解决的新问题,主要有RFID数据清洗方法、以数据为中心的检测技术、以事件为中心的检测技术,以及复杂事件处理系统等,并对今后的研究重点进行了展望。
