1. A method for transmitting data in a carrier sense multiple access wireless network wherein a plurality of data transmission devices respectively send at least one data frame at different moments from each other, wherein the method causing, by each transmission device when the transmission device is initialised, to perform:
loading a final value of a first counter, a final value of a second counter and a final value of a third counter, the final value of the first counter being identical for all the data transmission devices, the final value of the second counter being identical for all the data transmission devices and the final value of the third counter being different from each final value of the third counter of the other data transmission devices, the first, second and third counters having an initial value;
triggering the second counter as from its initial value, the second counter being reinitialised to its initial value,
when the second counter has arrived at its final value, triggering the first counter as from its initial value, the first counter being forced to its final value whenever the presence of data is detected on the medium if the second counter has arrived at its final value,
when the first counter has arrived at its final value, triggering the third counter as from its initial value, the third counter being reinitialised to its initial value and retriggered whenever the presence of data is detected on the radio medium,
transferring at least one data frame, when the first counter has arrived at its final value, and triggering the first counter as from its initial value.
