摘要
针对现有阅读器功率控制算法存在随机退避机制的不确定性、难以设置算法相关参数等不足,提出了一种改进的阅读器分布式功率控制(EDPC)算法.该算法通过合理设置阅读器的工作时序和改善阅读器对工作时隙的选择机制来提高阅读器功率控制的效率与可靠性.仿真实验结果表明,与DAPC、PPC算法相比,EDPC算法的检测范围明显扩大,检测所需时间大大减少,提高了系统的整体性能.
As the parameter setting, available power control algorithms for readers exist uncertain random backoff and insufficient in this paper presents an improved distributed power control algorithm marked as EDPC. In this algorithm, the working time sequence of the reader is reasonably set and the selection mechanism of working time slot is improved, thus increasing the efficiency and reliability of power control. Simulated results indicate that, as compared with the existing DAPC and PPC algorithms, the proposed algorithm enlarges the detection range of the reader, shortens the detection time, and improves the integrated performance of the reader system.
