The invention relates to a transmission control method of a set of transmitter/receiver systems of a local network comprising N transmitter/receiver systems wishing to transmit at least one data packet via the wireless local network, each transmitter/receiver system wishing to transmit said at least one data packet after a contention period during which a transmitter/receiver is or is not authorized to transmit the data packet of said transmitter/receiver, the method being characterized in that the contention period is broken down into R consecutive contention windows where R≧1, each contention window being broken down into K intervals of equal duration θ followed by an interval of duration δ, each contention window corresponding to a round r of contention; and in that the method comprises a step of determining the number K of intervals and the number R of contention windows, on the basis of the number N of transmitter/receiver systems wishing to transmit at least one data packet via the wireless local network.
