Dynamic Frame Slotted ALOHA (DFSA) is widely used Medium Access Control (MAC) mechanism in Radio Frequency IDentification (RFID) systems. In RFID DFSA, communication between RFID readers and tags is organized in the interrogation rounds contained of frames which are further divided into slots. Upon announcing the size of frame, RFID tags are randomly taking the spot, i.e. the slot of the given time frame and they respond back to the reader when that slot is being interrogated. DFSA throughput, defined as a ratio between the number of successfully read tags (one tag response in the slot) over the size of frame, is greatly influenced by the size of frame.
