Abstract: RFID (radio frequency identification devices) tag reader is very sensitive to the operating environment, which causes the produced RFID data flow unreliable, containing a large amount of missing words in reading, therefore, it’s necessary to cleanse the original data. An adaptive data cleansing algorithm based on sliding window is designed, which employs the sliding window technology and binomial distribution model to calculate the appropriate size of windows and dynamically adjusts the size of the window through the monitoring results of the subinterval windows and the states of the tags. Results show that this algorithm produces fewer errors on average than SMURF algorithm, that its performances are more superior and that its accuracy and stability are obviously improved.
