Abstract
Radio Frequency Identification (RFID) is an information exchange technology that leverages radio wave communication. The RFID system facilitates automatic identification and tracking of individuals and products by comprising two components- reader and tag. It also presents a viable solution for indoor localisation. In this study, we propose a novel, low-cost, range-free localization scheme tailored for three-dimensional (3D) positioning within high-complexity indoor RFID environments. The scheme employs a network of RFID tags with known locations as reference points to estimate the 3D coordinates of a target object enclosed within a hexahedral space and tagged with an RFID. Additionally, we assess the localization error to ensure robust performance. Simulation results demonstrate that our algorithm achieves notable accuracy, showcasing its effectiveness in addressing the challenges of 3D localization. This study contributes a scalable and cost-efficient approach to RFID-based localization, paving the way for advancements in smart indoor environments.
