The invention relates to the estimation of a time-variable physical quantity by a distributed system comprising a centralized platform and a set of distributed measurement devices each communicating with the platform via a communication network, on the basis of the measurement (), by each device of the set, of a local datum representative of the physical quantity, the collection () by the centralized platform, over a predetermined sampling period, of measurement samples originating from a subset of devices of said set via said communication network, and the estimation () of the physical quantity over the sampling period on the basis of the collected samples. According to the invention, each device of said set executes (), in each sampling period, a local algorithm deciding randomly and based on a sending probability associated with each device, whether the corresponding measurement device is part of said subset. The physical quantity is estimated on the basis of the measurement samples collected and the predefined sending probability for each device belonging to the subset.
