射频识别(RFID)系统正在成为主要的对象识别机制,特别是在供应链管理中。然而,RFID自然会产生大量的重复读数。从RFID数据流中删除这些重复的数据是至关重要的,因为它不会向系统提供新的信息并浪费系统资源。现有的处理方法不能满足处理海量RFID数据流的实时性要求。我们提出了一种数据过滤方法,可以有效地检测和删除RFID数据流中的重复读数。实验结果表明,与现有方法相比,该方法有明显的改进。
Radio frequency identification (RFID) systems are emerging as the primary object identification mechanism, especially in supply chain management. However, RFID naturally generates a large amount of duplicate readings. Removing these duplicates from the RFID data stream is paramount as it does not contribute new information to the system and wastes system resources. Existing approaches to deal with this problem cannot fulfill the real time demands to process the massive RFID data stream. We propose a data filtering approach that efficiently detects and removes duplicate readings from RFID data streams. Experimental results show that the proposed approach offers a significant improvement as compared to the existing approaches.
