Abstract
RFID (radio frequency identification technology) is a non-contact automatic identification technology. During the Tag identification process, an effective anti-collision method will make a significant contribution to the RFID system in accelerating the identification speed. This paper proposes a method to improved RFID anti-collision protocol that incorporates a NOMA (non-orthogonal multiple access) technique, which is based on ISO 18000-6C standard. This paper simulates the method and compares it with traditional scheme of 18000-6C18000-6C. Through our simulations, NOMA-based RFID Tag identification method outperforms Traditional schemes in both the average access slot efficiency and time efficiency. It can solve serious collision under massive Tags numbers and improve system efficiency. It also can be conveniently applied to engineering implementations.
