GROUPED DYNAMIC FRAME SLOTTED ALOHA ALGORITHM BASED ON RANDOM NUMBER
当读写器识别范围内同时存在大量标签时容易引起碰撞问题,导致系统吞吐率恶化.针对此问题,提出基于随机数的分组动态帧时隙ALOHA算法.在原有算法基础上,使标签携带多级随机数,将多数空闲时隙转化为成功时隙,减少时隙消耗数,提高系统吞吐率;提出改进的帧长与标签数对应关系,提高系统稳定性.仿真实验结果表明,该算法表现出较好的吞吐率与稳定性,系统吞吐率由36.8%提高至55.3%.
When there are a large number of tags in the recognition range of the reader,it is easy to cause the collision problem,which leads to the deterioration of the system throughput.To solve this problem,a grouped dynamic frame slotted ALOHA algorithm based on random numbers is proposed.Based on the original algorithm,the tags carried multiple random numbers to convert most idle time slots into successful time slots,which could reduce the time slots consumption and improve the system throughput rate.An improved corresponding relation between frame length and label number was proposed to improve the system stability.The simulation results show that the algorithm has good throughput and stability,and the throughput of the system increases from 36.8%to 55.3%.
