Abstract: Radio frequency identification(RFID) is one of the key technologies in Internet of Things. The uncertainty and mass of RFID original data limit the development of technology seriously. 13y analyzing the uncertain data characteristics,an RFID data cleaning strategy under shunting mechanism was established. The strategy introduces the cleaning queue concept, and according to the cleaning nodes' judgment conditions it can choose the optimal cleaning line. Since it needn't to travel all the cleaning nodes in cleaning system, it saves much time of data transmission and waiting. The experimental results show that the strategy can ease the pressure of data transmission, and improve the efficiency of data cleaning greatly.

Key words: RFID, Internet of things, Uncertain data, Shunting mechanism, Cleaning strategy
