Abstract
A compression method for resource constrained local area networks (LANs) of an Industrial Internet of Things (IoT) reduces the volume of raw data sent from “Things” to connection points on the LAN. Applications include industrial processes, and typically include multiple sensor nodes. Sensors on machines wirelessly send data to a base station using a wireless LAN. A computer or server in communication with the wireless LAN computes the health of a machine based on the data received. The method operates by taking advantage of unique similarities between sequential groups of certain types of data that can be sent on the LAN. Mathematical operations are performed on the baseline and subsequent data sets to determine similarities. A difference is taken between the baseline and subsequent data sets, and this difference is compressed and sent to the base station where the original data is reconstructed using the baseline data and uncompressed difference data.
