Research on Indoor Positioning Technology of RFID Nodes in the Internet of Things (IoT)

With the emergence of Internet of Things (IoT) applications that provide services based on location information. The Radio Frequency Identification (RFID) technology is considered as one of the key technologies of the Internet of Things' sensing layer. In the Internet of Things (IoT) domain, further research on the positioning technology of RFID nodes has significant practical implications. Initially, this article analyzes a variety of existing RFID indoor positioning technologies and then focuses on fingerprint positioning technology to improve the traditional fingerprint positioning algorithm and finally demonstrates that the improved algorithm delivers more accurate positioning through MATLAB simulation.
