In RFID systems, tag anti-collision algorithm is significantly important for fast tag identification. In this paper, we research a robust tag estimation method and the PRQT algorithm, and propose prefix-maximized query-tree (PMQT) tag anti-collision protocol. The simulation results show that the system efficiency of PMQT is higher than the previous protocol about 18%–30%. In addition, PMQT algorithm...
With the development of radio frequency identification (RFID) technology, RFID systems have been used in various applications. But the tag collision problem greatly affects the performance of many RFID systems, especially in large scale tag identification environments. In this paper, we propose two new efficient tag anti-collision protocols, i.e., the assigned tree slotted Aloha (ATSA) protocol and...
