Optimizing Adaptive Power Control for Enhancing Robustness in RFID Sensing

In dense RFID systems, power control provides an effective means for maintaining communication efficiency and preventing reader-to-reader and reader-to-tag interference. Traditional RFID systems often operate at fixed power levels, which can lead to communication bottlenecks and inefficient tag reads in dynamic environments. This paper proposes an adaptive power control technique to improve the system performance by dynamically adjusting the transmit power based on environmental conditions, tag distance, and network congestion. Simulations and experimental results demonstrate that the proposed approach improves tag read rates, reduces interference, and enhances system robustness in dense environments.
