摘要
射频识别(RFID)数据流处理技术中基于复杂事件处理机制(CEP)的方法受到业界广泛关注。针对射频识别数据的特点以及目前射频识别复杂事件处理方法的不足,通过扩展和改进高效模式匹配算法Rete,提出了复合事件处理方法ERD。该方法实现了事件检测机制与中间结果共享机制的有机统一,从而达到了提高系统整体检测效率的目的。仿真实验证明该方法具有较好的效果。
Radio Frequency Identification (RFID) data stream processing technology especially Complex Event Processing (CEP) -based approach is a hot spot in the RFID applications. This paper analyzed the characteristics of RFID data and the disadvantages of the previous CEP-based methods. Moreover a complex event processing method ERD was presented, which combined the detected event and intermediate result sharing mechanism organically and improved the detection efficiency of the overall system. Simulation results validate the effectiveness of the proposed method.
