| Abstract: | An accurate and efficient Dynamic Framed-Slotted ALOHA(DFSA) anti-collision algorithm is proposed based on unequal timeslots in Radio Frequency IDentification(RFID) system.Considering the influence of idle and collided timeslots on RFID system efficiency,the algorithm adopts an optimized DFSA anti-collision strategy based on unequal timeslots,which determines frame length by optimized parameter and unread tags,performs tag estimation with optimized Chebyshev's inequality,and analyses the process of identifi... |
