Abstract: A method and a system for determining sampling schemes of a network-connected measurement unit based on time-varying predictability of the measured signals are provided herein. The method may include the following steps: sampling, via a sensor, a metric indicative of a physical property of an infrastructure system, wherein the sampling is carried out over a training period, at an original sampling scheme; determining, based on the training period, in which future time ranges, whether said metric is predictable within a predefined threshold; and adjusting the original sampling scheme, so that the more said metric is predictable in a future time range, the less said future time range is sampled, to yield an updated sampling scheme. In another embodiment, the prediction of the signal may be used to postpone the transmitting of measurements by the local sensor devices whenever the new measurements do not exceed a predefined threshold beyond the predicted values.
