Abstract
Aiming at the problem that dynamic frame slotted ALOHA algorithm (DFSA) delay is too big and its hardware requirement is too high when tag number increases.The grouping dynamic framed slotted ALOHA algorithm (GDFSA) was proposed.The algorithm determined the number of the tags'group and identified the tags by grouping through the tags quantity estimation method and according to the optimum frame length.The test results showed that GDFSA algorithm which could effectively solve the problem of the tag collision in radio frequency identification (RFID) system and improved the identification efficiency and channel availability.
