| 摘要: |
| 对超高频RFID系统中ISO18000-6C标准使用的时隙Aloha算法进行改进,并用仿真试验来检验系统的性能。改进的算法运用切比雪夫不等式估计现场未识别的标签数目,根据最优帧长原理动态地调整帧时隙数和分群数。在标签数目相同情况下,改进算法后系统的吞吐率与信道利用率都有所增高。 |

| Abstract: |
| This research paper improves the slotted ALOHA anti-collision algorithm that is used in ISO18000-6C protocol, and the simulation experiment is used to test the performance of the algorithm. The number of the tags in the identification field of reader are estimated by using Chebyshev-Inequality. According to the optimal frame length principle, the number of slots and groups in every frame are dynamically adjusted. In the condition that the tags are the same amount, the throughput rate and the channel utilization rate of system increase after improving the algorithm. |
| Key words: anti-collision algorithm radio frequency identification (RFID) number of slots |
