Abstract:

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.
