优化的动态帧时隙ALOHA防碰撞算法
Optimized dynamic framed slotted ALOHA anti-collision algorithm
摘要
Abstract
To improve the estimation of the number of tags in the dynamic framed slotted ALOHA anti-collision algorithm, this paper used dynamic adjustment mechanism to automatically adjust the formula coefficient of estimation of the number of tags for the problem of the length of the frame slot which the reader should be used in the next polling cycle. For the problem of higher collision rate when the frame length equal to the number of tags, it optimized the frame length by including the query command time in the total frame time. The simulation results show that the optimized DFSA algorithm reduces total delay time and the collision rate, improves system efficiency, especially in the number of tags are less.关键词
