Abstract:

The original RFID data must be cleaned to ensure the accuracy of data due to the problem of RFID missing data in reading.In view of problems that exist in the SMURF,which is the most effective cleaning algorithm based on slidingwindow in the current,this paper proposes an improved algorithm for accurately detecting the tag's dynamic changing with a more reasonable mechanism to set slidingwindow.The experimental results show that the proposed algorithm enjoys fewer errors and better performance than the SMURF algorithm during the cleaning.
