The article introduces a new method called Double Polling-Based Tag Information Collection for Sensor-Augmented RFID Systems. This method aims to efficiently gather important information from objects with RFID tags. By using a double polling mode, the researchers were able to simultaneously query two tags, making the process more efficient. They also developed techniques to shorten the length of the polling vectors, which further improved the data collection process. Through theoretical analyses and simulations, the researchers showed that their protocols are effective in improving the utilization of polling vectors in RFID systems.
