| Abstract: | ALOHA anti-collision algorithm is an important RFID anti-collision algorithm in RFID （Radio Frequency Identification）. The algorithm is simple and easy to implement, but the system throughput is low. The algorithms of ALOHA （DFSA） algorithm are studied and improved. In this paper, the ALOHA algorithm and its improved algorithm are summarized in detail. The current research method is deduced and experimentally simulated. In this paper, the algorithm of key link tag estimation algorithm for Dynamic Frame Slot ALOHA （DFSA） algorithm is carried out and concluded detailedly. Finally, the current research direction is put forward according to the present situation. |
