Abstract
Radio frequency identification (RFID) technology is a kind of non-contact identification technology, which has been widely applied in logistics management, access control system and other fields. However, when multiple tags response the RFID reader simultaneously, the superposition of signals will deduce reader’s incorrect reception, which is called collision. Dynamic frame slotted ALOHA (DFSA) algorithm is a effective anti-collision algorithm in RFID system, but its’ high system efficiency relies on the reliability of the tags’ number estimation. Some researches propose a frame break policy for ALOHA-based RFID system, which breaks the frame early when judging that the current frame length is not appropriate through slot-by-slot estimation of number of tags and is called SbS-DFSA. Here, we find some improvement space of SbS-DFSA, and make it more efficient by modifying some details. The simulation shows that our modification is efficient and improves the performance practically.
