RFID data fusion algorithm based on spatio-temporal semantics in internet of things

Information sensing and processing of Internet of things (IoT) is the most basic function, which is of special significance to the spatio-temporal characteristics. Used spatio-temporal correlation of RFID data, based on the perception data semantic representation, an IoT RFID data fusion processing algorithm based on spatio-temporal semantics has been proposed. Firstly, the data of the same time, different space position is used for spatial fusion processing, then the data of the same equipment, different time is used for time fusion processing in the order of time. The experiment results indicate that our algorithm can effectively remove redundancy data, reduce the amount of data and relieve the waste of system resource. And the proposed method has a certain feasibility and validity.
