随着无线转频识别技术RFID的广泛应用,相应的研究工作也逐渐铺开。由于RFID数据具有流特性、海量性和语意丰富性等特点,在现实世界中获取符合研究要求的数据集并非易事。通过分析RFID数据的特点、阅读器的物理特性和各种典型应用场景,建立了RFID数据仿真的数学和物理模型,并提出了基于CSIM仿真开发包构建大规模RFID数据生成器的实现方案。实验结果表明,该生成器具有较高的准确性和性能。
With the widely usage of RFID ( radio frequency identification) technology, related research has become more and more popular. Since RFID data contains streaming, magnanimity and semantic features, it is difficult to fetch data set that fit research requirements from real world. This paper analyzed the characteristic of RFID data, readers and various kinds of typical application scenarios, created the mathematics and physics model of RFID emulation, then proposed an implementation of RFID data emulator based on CSIM. Our preliminary experiments demonstrate that it is accurate and efficient.
