Research of the Distributed RFID Complex Event Progressing Technology

目前RFID复杂事件处理技术的研究主要针对集中式的处理。集中式RFID复杂事件处理技术对于海量RFID数据的处理具有很多局限性,主要表现为网络通讯代价高和处理效率低。针对集中式RFID复杂事件处理存在的问题,本文研究了分布式环境下RFID复杂事件处理的关键算法,采用一种Pull(抽取)类型的数据通讯模型来降低通讯代价,在此基础上提出了两种分布式的RFID复杂事件处理算法。实验结果表明,本文提出的分布式RFID复杂事件处理算法比集中式复杂事件处理算法更有效。

The current study of the RFID complex event processing technology usually focuses on the centralized processing technology.For the applications of massive data processing,there are some limitations in such a technology,such as mainly performance in high communication cost and low processing efficiency.In this paper,we study the crucial algorithm of distributed RFID complex event processing on this problem,use a kind of data communication model named Pull to reduce the communication cost,and proposes two algorithms in distributed RFID complex event processing to improve the processing efficiency based on this model.The experimental study shows that the performance of the proposed algorithms is more effective than the centralized processing algorithm.
