复杂事件处理(CEP)是一个新兴的技术领域,用于处理大量的简单事件,并从其中整理出有价值的事件。RFID事件和传统事件相比具有海量、时间性和空间性、数据不准确等特征。针对RFID事件的相关特征进行研究,建立一个可扩展的基于规则的RFID复杂事件处理系统是非常必要的。从复杂事件的描述模型、处理框架、上下文语义、检测方法等方面总结了国内外RFID复杂事件处理的研究现状,分析了目前的研究存在的不足,并且针对SASE的复杂事件算法存在的三点不足进行了改进。实验讧明相关的改进对简单数据集是有效的。
Complex Event Processing(CEP) technology is a new technology which is applied in processing large volume primitive events and picking out valuable semantic events.In comparison with traditional events,RFID events have the following characteristics:large volume,temporal & spatial,inaccurate ete.lt is necessary to do some researches on these characteristics and build an extensible CEP framework for RFID events.ln this paper,the current researches on describing models,processing framework,pa- rameter context,detecting method of RFID CEP are summarized.This paper picks out three problems of SASE and brings out some enhancing methods.These methods are proved efficient by some experiments.
