Research and Implementation of an RFID Simulation System Supporting Trajectory Analysis

Radio Frequency Identification (RFID) has been playing more and more important roles in domains such as supply chain management, commodity retail and health custody. RFID data can support functions such as object location, object tracking and trajectory analysis. However, at some point, to deploy many RFID devices into a real application scenario would be very difficult. In this paper, we present a RFID simulation system which could support effective data analysis and help users judge the effectiveness of deployment. This system implements part of ISO 180006C communication protocol and supports the path loss, backscatter, capture and tag mobility models. It provides a user-friendly visual platform for users to build their own virtual scenarios and deploy RFID devices into it. Further more, in order to improve the efficiency of operations in the application scenarios, we combine R-Tree with TSB-Tree to support the RFID object location and the trajectory analysis.
