A New Frame Size Adjusting Method for Framed Slotted Aloha Algorithm

In this paper, a new frame size adjusting method is proposed for framed slotted ALOHA algorithm in RFID system. This method does not predict the number of tags. The reader just use the current frame size and the total number of successful slots, idle slots and collision slots in current frame to select a more appropriate frame size to continue the inventory of tags in a new frame. The proposed adjusting method can be easily carried out, and simulation results show that the proposed algorithm consumes fewer time slots as compared to previous work.
