摘要
详细介绍了基本ALOHA算法、时隙ALOHA算法、帧时隙ALOHA算法和动态帧时隙ALOHA算法基本原理和系统效能,分析了上述4种算法各自特点.提出了基于分组的动态帧时隙ALOHA算法,该算法根据标签数量对标签进行分组,并动态匹配最佳帧长.仿真结果表明,改进后算法系统具有吞吐率高、不受标签数量限制、节约帧时隙等优势.
This paper introduces the basic ALOH algorithm, slotted ALOHA algorithm, frame slotted ALOHA algorithm and dynamic frame slotted ALOHA algorithm in details, as well as their basic principle and system effectiveness, and analysis their characteristics. Based on the dynamic frame slotted ALOHA packet algorithm of this paper is presented, labels are grouped according to the number in the algorithm, and dynamic matching optimal frame length, the simulation results show that the improved system has the advantages of high throughput, unrestricted in the number of labels, saving time slots of a frame, and so on.
