摘 要: | 本文在分析传统 ALOHA 算法的基础上,提出了一种基于碰撞预检测的分组动态帧时隙 ALOHA 防碰撞算法。该算法通过分组限制响应的标签数量,并且在组内预先发送一个短暂的碰撞检测帧去检测帧内的情况,达到在阅读器与标签之间建立一个完全无碰撞信道的目的。仿真结果表明,当标签数量较大时,该算法能有效减少总数据传输量,提高识别效率。

Packet Dynamic Frame Slotted ALOHA Anti-collision Algorithm Based On Pre-detection |

Abstract: | This paper proposes a packet dynamic frame slotted ALOHA anti-collision algorithm based on Pre-detection by analyzing traditional ALOHA Algorithms.It can limit the number of response tags through grouping,and send a short collision-detection frame in advance to detect the in-frame situation,in order to create a collision-free channel between readers and tags.Simulation results show that,when the number of tags is large,the algorithm can effectively reduce the total amount of transferred data and inprove the identification efficiency. |
