有源电子标签具有传输距离远、数据处理能力较强等特点。因此，远距离RFID系统被用于集装箱扫描和冷链物流等场合。但是有源标签一般以恒定功率工作，会导致电能的不必要消耗。针对该问题，提出一种有源标签的分布式功率控制算法，通过运用matlab对算法进行仿真分析，结果表明该算法能明显降低有源电子标签的功耗从而延长标签使用寿命。所以随着物联网技术的高速发展，该算法具有一定的商业应用价值。
有源電子標籤具有傳輸距離遠、數據處理能力較彊等特點。因此，遠距離RFID繫統被用于集裝箱掃描和冷鏈物流等場閤。但是有源標籤一般以恆定功率工作，會導緻電能的不必要消耗。針對該問題，提齣一種有源標籤的分佈式功率控製算法，通過運用matlab對算法進行倣真分析，結果錶明該算法能明顯降低有源電子標籤的功耗從而延長標籤使用壽命。所以隨著物聯網技術的高速髮展，該算法具有一定的商業應用價值。

Active RFID tag has the features of long communication distance and high data processing ability. Therefore, the long-range RFID system is used for container scanning, cold-chain logistics and other occasions. However, the active tag always work at constant power, and this would lead to unnecessary power consumption. To solve this problem, a distributed power control algorithm for active tag is proposed. Simulation with matlab shows that the proposed algorithm could obviously reduce the power consumption and prolong the service life of the active e-tag. So with the rapid development of IoT (Internet of things) technology, this algorithm would has certail value in commercial applications.
