RFID动态标签估计防碰撞算法

针对无线射频识别(RFID)过程中标签之间的碰撞问题，提出一种新的RFID防碰撞算法。利用二进制碰撞算法动态地估计一部分将要被识别的标签数，通过标签生成的随机数对其进行分组，并识别该部分标签。实验结果表明，该算法能有效减少冲突发生的概率，识别标签的效率为42.5%~42.8%。

Anti-collision Algorithm for RFID Dynamic Tag Estimation

This paper proposes a new Radio Frequency Identification(RFID) anti-collision algorithm to resolve the collision problem in the process of tag identification.The proposed algorithm makes the use of binary collision algorithm to estimate the number of the partial tags which are to be identified and use the multi-branch tree algorithms to identify those tags.Experimental results show that the algorithm reduces the probability of the conflict and the identification tag efficiency is 42.5%~42.8%.
