摘要
为进一步提高物联网标签识别防碰撞性能,通过对二进制树防碰撞算法及其改进算法的研究和分析,提出一种改进型位锁定物联网标签防碰撞算法。该算法通过在位锁定防碰撞处理前,将所有待识别标签按比特位之和进行奇偶分组,以减小标签碰撞的发生,并提高一次识别2个标签的能力。仿真实验表明:改进后算法的标签识别性能优于原算法,特别是在标签较集中时,这种算法具有更明显的优势。
To further enhance the performance of the Internet of things tag identification anti-collision,by researching and analyzing the binary tree anti-collision algorithm and its improved algorithms,an improved bitlocked tag anti-collision algorithm is proposed.Before processing of bit-lock anti-collision,the algorithm divides all the identification tags into two groups according to the parity of the bit sum of each tag,to reduce the occurrence of tag collisions and improve the ability to identify two tags one time.Simulation results show that the tag identification performance of the improved algorithm is better than the original algorithm,this advantage is more obvious when the tag is more focused.
