| 摘 要： | 基于碰撞识别算法系列,提出改进型自适应标签识别算法(Improved Adaptive Collision Tree Algorithm,IACT).算法通过优化查询前缀,消除了自适应碰撞标签识别算法在四叉树搜索产生的空时隙查询,从而减少了算法的时间复杂度,提高识别效率.通过理论推导和计算机仿真可知,该算法比自适应标签识别算法(Adaptive Collision Tree Algorithm,ACT)有着明显的优化.

| Abstract: | A novel improved adaptive collision tree algorithm (IACT) is proposed for RFID tags-reading based on adaptive collision tree algorithm. The improved algorithm reduces idle time slots which occurs in adaptive collision tree algorithm (ACT) by optimizing the prefix-query. So, the proposed algorithm reduces the time complexity and improves the efficiency of recognition in RFID system. By mathematical analysis and simulation, it proves that the improved adaptive collision tree algorithm (IACT) has a better performance than adaptive collision tree algorithm (ACT) for RFID tags-reading. |
