Method for routing data broadcast by a first device and received by a second device during a first time window, the first, respectively the second, device forming a first, respectively a second, node (Ci) of a network of a plurality of nodes able to communicate through a wireless communication channel comprising the following steps, implemented by the second device: - selection of a time interval from among a set of predefined time intervals of a second time window following said first time window; said time interval (ΓΓ) being selected by random drawing, in accordance with a defined probability law, of a value identifying said interval, the second time window comprising a predetermined number N of predetermined consecutive time intervals, a rank being associated with an interval as a function of a position of said interval with respect to the start of the second time window, the probability of selecting the interval of rank k+1 from among the N intervals being greater than or equal to the probability of selecting the interval of rank k, the probability of selecting a value identifying an interval being determined as a function of a value representative of a quality of the signal received during the reception of said data, of the number of intervals and of said value identifying the interval and said value representative of a quality of the signal received representing a parameter for controlling a rate of growth of the probability law; - monitoring of said channel between the end of said first time window and said selected time interval so as to detect the presence or the absence of a signal on said channel; - broadcasting of said data from an instant of said selected time interval in case of detection of absence of signal and - non-broadcasting in case of detection of presence of signal. - selection of a time interval from among a set of predefined time intervals of a second time window following said first time window; said time interval (ΓΓ) being selected by random drawing, in accordance with a defined probability law, of a value identifying said interval, the second time window comprising a predetermined number N of predetermined consecutive time intervals, a rank being associated with an interval as a function of a position of said interval with respect to the start of the second time window, the probability of selecting the interval of rank k+1 from among the N intervals being greater than or equal to the probability of selecting the interval of rank k, the probability of selecting a value identifying an interval being determined as a function of a value representative of a quality of the signal received during the reception of said data, of the number of intervals and of said value identifying the interval and said value representative of a quality of the signal received representing a parameter for controlling a rate of growth of the probability law; - monitoring of said channel between the end of said first time window and said selected time interval so as to detect the presence or the absence of a signal on said channel; - broadcasting of said data from an instant of said selected time interval in case of detection of absence of signal and - non-broadcasting in case of detection of presence of signal.
