摘要
为了进一步提高防碰撞算法的性能,对随机标签防碰撞算法进行了研究,分析了随机标签防碰撞算法的优点与缺点.其中,动态帧时隙算法(DFSA)存在随着标签数目的增多,所需要的时隙数目急剧增加的缺点,针对这一问题,提出了一种动态帧时隙算法的分集改进方法.仿真结果表明,改进方案减少了系统识别标签所需要的时隙数量,提高了算法性能.
To further improve the performance of anti-collision algorithm,this paper studied the random anti-collision algorithm,analyzed the advantages and disadvantages of the random anti-collision algorithm,which the slots number of dynamic framed slotted algorithm（DFSA） have dramatic increased if the number of tags were increased.To solve this problem,this paper proposed a sub-set of ways to improve the framed slotted algorithm.The results of simulation showed that improvement program reduce the slots number of system needed to identify the tags,and improved the performance of anti-collision algorithm.
