摘要
阅读器碰撞问题一直是射频识别系统中迫切需要解决的问题,它会显著降低系统的性能,在大规模场景中依旧存在算法复杂度高,识别效率低下的问题。为提高系统整体性能,该文提出基于动态调度的阅读器防碰撞算法,提出反向权重概念,用来表示阅读器碰撞情况。重新定义了阅读器优先级定义,实现动态调度。仿真结果表明,与传统的阅读器防碰撞算法相比,该算法的识别效率提高了23.45%,吞吐量提高了10.77%。
Reader collision problem has always been an urgent problem to be solved in radio frequency identification system,it will significantly reduce the performance of the system,large⁃scale scenes still have the problems of high algorithm complexity and low recognition efficiency.In order to improve the overall performance of the system,this paper proposes a reader anti⁃collision algorithm based on dynamic scheduling,and puts forward the concept of re⁃verse weigh to represent the reader collision.Redefine the reader priority definition to achieve dynamic scheduling.Simulation results show that,compared with the traditional reader anti⁃collision algorithm,the recognition efficiency of this algorithm is improved by 23.45%,and the throughput is improved by 10.77%.
