摘要：

In RFID systems, collision resolution is a significant issue in fast tag identification. This letter presents it dynamic frame-slotted ALOHA algorithm that uses a collision factor (DFSA-CF). This method enables fast tag identification by estimating the next frame size with the collision factor in the current frame. Simulation results show that the proposed method reduces slot times Required for RFID identification. When number of tags is larger than the frame size, the efficiency of the proposed method is greater than those of conventional algorithms.
