Abstract: SMURF(Statistical sMoothing for Unreliable RFid data) algorithm based on adaptive sliding-window needs to set a threshold manually.The value of has no effect on the smoothing results to the static RFID tags,but it will cause errors when the tags are dynamic.To solve the shortcomings above,the paper proposed DSUMRF(Dynamic tags-based SMURF) algorithm based on dynamic tags.Above all,SMURF algorithm takes major considerations of lost reading and misreading,it is not related to the processing of redundant RFID data.This paper proposed a framework of redundant data cleaning based on DSMURF algorithm.The results of the experiments show that DSMURF performs better than SMURF to the dynamic tags.
