    Abstract: Systems and storage media containing instructions for asset tracking are provided. An example system includes a server and an asset tracking device onboard an asset. The asset tracking device to receive raw data pertaining to the asset, determine a dynamic group of carry-over data points, derived from the raw data, to be used in the performance of a dataset simplification algorithm on the raw data, perform the dataset simplification algorithm on a set of data that contains the raw data and the dynamic group of carry-over data points to determine one or more data points in the set of data to be recorded, and transmit the recorded data points to the server.

    Abstract: Methods and systems for simplifying data collected from assets are provided. An example method involves receiving a simplified set of data at a server. The simplified set of data is generated by application of a dataset simplification algorithm on raw data obtained from a data source at an asset upon a determination that a recently obtained point in the raw data differed from a corresponding predicted point predicted by extrapolation based on previously saved points included in one or more previously generated simplified sets of data by an amount of extrapolation error that is limited by an upper bound that is fixed as the raw data is collected over time. The method further involves receiving a request for a status of the asset and extrapolating a status of the asset based on the simplified set of data in response to the request.
