%X To improved the estimate of the number of tags in the dynamic framed slotted ALOHA anti-collision algorithm, using dynamic adjustment mechanism to automatically adjust the formula coefficient of estimate of the number of tags, solved 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 total delay time and the collision rate reduced, system efficiency improved, especially in the number of tags are less.
