Abstract:
A method and an apparatus for preventing tag collision in a Radio Frequency IDentification (RFID) system are provided. A method of a reader for preventing the tag collision in the RFID system includes modifying variables such that every tag responds in the same slot, measuring a power of tags received in the same slot, allocating slots by predicting the number of the tags based on the measured power, and reading the tags in the allocated slots.
