1. A method comprising:
- managing transmissions of a plurality of sets of measurements performed iteratively by a measurement sensor communicating with a collection device via a radio network, each set of measurements being performed with a respective iteration at a regular time interval, wherein managing comprises the following acts performed by the measurement sensor;
for each set of measurements, determining a respective date of transmission for that set of measurements, the determination of said respective date of transmission for each set of measurements comprising a determination of a time window starting from an instant which is a function of a measurement date of one of said sets of measurements, or a function of a determined respective date of transmission of a preceding set of measurements of the plurality of sets of measurements, and a determination of a random value according to a random distribution law over said window, said respective date of transmission being said random value, wherein the determined time window has a length that is greater than said regular time interval; and
transmitting by the measurement sensor a message relating to at least one set of measurements over the radio network, on one of the respective dates of transmission determined for the plurality of sets of measurements, wherein the message comprises a measurement report relating to the at least one set of measurements performed by the measurement sensor.
