An improved dynamic frame slotted ALOHA algorithm

摘要: 针对目前动态帧时隙ALOHA算法所需时隙数较多的问题,基于电子标签数量和发生碰撞概率的关系,提出了一种改进的动态帧时隙ALOHA算法.在改进算法中,帧长的确定不需事先估算电子标签的数量,而只需根据上一帧中电子标签发生碰撞的概率来确定.仿真试验表明,改进算法所需的时隙数和计算量较少.

Abstract: Aiming at the problem that the dynamic frame slotted ALOHA algorithm required more timeslots,an improved dynamic frame slotted ALOHA algorithm was proposed through analyzing the relation between the number of electronic tag and probability of collision,which determine the length of frame don't need estimate the number of tags,only need a frame timeslot conflict probability.Simulation results showed that the improved algorithm has less timeslot and computation.-
