IoT Data Validation Using Spatial and Temporal Correlations

The Internet of Things (IoT) is the extension of Internet connectivity to physical devices and everyday objects. These devices composed by sensors, software and network connectivity can acquire, store and exchange data among them over the Internet. One of the main tasks of an IoT system consists in the continuous exchange of data and information of various kinds. The correctness of the value produced by the sensor is a crucial factor for the operation and reliability of the entire IoT system. This paper presents a centralized data validation algorithm which attempts to use spatial and temporal correlations to compensate for error on the data.
