Abstract
A method which constructs, in each transmitter/receiver of a mobile body or vehicle, information tables recording the changes undergone by a radio channel by memorizing, during consecutive time intervals of a determined duration dT that are smaller than the period of recurrence T, of the statuses of the radio channel, namely 'in collision', 'busy' or 'free'. The method then sets fixed transmission instants in each transmitter/receiver, these fixed transmission instants being temporally spaced out at intervals equal to the recurrence period T, to predict the status of the channel for each fixed transmission instant as a function of the status of the channel memorized at the instant preceding it with a temporal shift equal to the period T, and in deciding to transmit at this instant if the predicted status of the channel is not a status of collision or to transmit at an instant deferred with respect to the predicted instant if the opposite is the case.
