在动态分帧时隙Aloha RFID系统中,关键技术可分为两部分:精确估计标签数量和确定最佳帧长。对于标签数量的估计,本文利用三种风险函数提出了三种贝叶斯估计,并对估计进行了改进,降低了计算复杂度。为了确定最佳帧长,本文推导了在空闲时隙、冲突时隙和成功时隙的持续时间不相同的情况下,使系统达到最大信道利用率的最佳帧长。在我们的模拟中,与几个传统的标签估计的比较表明,所提出的贝叶斯标签估计有较小的误差。此外,改进的估计具有较低的计算复杂度,其估计性能没有降低。仿真结果还表明,推导出的最佳帧长保证了最大的信道利用效率。
In a dynamic framed slotted aloha RFID system, the key technique can be divided into two parts: precisely estimating tag quantity and determining an optimal frame length. For estimating tag quantity, this paper uses three risk functions to propose three Bayesian estimates, and improves the estimates to reduce computational complexity. For determining an optimal frame length, this paper derives an optimal frame length, which can make the system achieve maximum channel usage efficiency under the condition that the durations of an idle, a collision and a successful slot are not identical. In our simulations, comparison with several conventional tag estimates shows that the proposed Bayesian tag estimates have less error. In addition, the improved estimates have lower computational complexity and their estimate performance is not reduced. The simulations results also indicate that the derived optimal frame length guarantees the maximum channel usage efficiency.
