ABSTRACT:
The present invention relates notably to a method for sharing a transmission medium between communication apparatuses having an identifier, each adapted on the one hand to transmit messages by device of the transmission medium, during so-called "transmission" phases, and/or on the other hand to receive messages by device of the transmission medium, during so-called "reception" phases. Each communication apparatus stores, in each reception phase, and associated with identifiers, activity states representing the last messages transmitted by the communication apparatuses having these identifiers, in their own transmission phases. In a so-called "transmission preparation" phase preceding each transmission phase, each communication apparatus determines, according to first predetermined rules taking into account at least certain of the said activity states, at what moment it can transmit a message on the transmission medium.
