Abstract:

Aiming at the problem that the redundant data in the radio frequency identification (RFID) data stream of internet of ship affect the work efficiency,this paper proposes a RFID redundant data cleaning algorithm based on improved Bloom Filter.The matrix Bloom Filter model is constructed based on the analysis of the traditional Bloom Filter,and the cleaning process of the redundant data is given based on this model.Simulation experiment shows that the larger RFID data flow,the more obvious the data cleaning effect.
