摘要
在无线射频识别技术中,经常需要标签防冲突算法以解决标签碰撞问题。在该类算法中,为使得系统识别效率达到最大,往往需要预先估算出未识别标签数量。本文在研究多种标签估计算法上,提出一种通过研究某帧长内成功时隙、空闲时隙之间的关系,估算标签数目,同时发现在理想识别效率下,空闲时隙和成功时隙相等。仿真对比了Schoute算法,本文算法拟合实际标签总数的效果稍好。
In RFID technology,tag collision prevention algorithm is often needed to solve the problem of tag collision.In this algorithm,the number of unrecognized tags is often estimated in advance in order to maximize the system recognition efficiency.In this paper,multiple tag estimation algorithms are studied,and a method is proposed to estimate the number of tags by studying the relationship between the successful time slot and the free time slot in the length of a frame.It is also found that the free time slot and the successful time slot are equal under the ideal identification efficiency.The simulation compares Schoute algorithm,and the algorithm in this paper has a slightly better effect of fitting the actual total number of tags.
