ABSTRACT:
A method whereby a moving body searches for an unoccupied time slot in a time-division communications channel for the transmission of a message. The moving body participates with other moving bodies located in the same geographical zone in an anti-collision system with the time being conventionally divided into reproducible time periods T. Each period includes a number N of time slots reference 1, 2, 3 . . . i . . N with the access to a time slot for the transmission of a message from the moving body being accomplished by identifying an unoccupied time slot during at least one listening period T, followed by a random choice of one slot i from among the slots identified as being unoccupied. For at least one period after the moving body has occupied slot i, the time of this slot is divided randomly into reception sub-slots R and transmission sub-slots E. As long as no transmission from another moving body is received during the reception sub-slots R, a transmission is begun or continued during the following transmission sub-slots E of the current slot i and slot i is kept during the subsequent period. On the other hand, if a transmission is received from another moving body during a reception sub-slot R, there is no transmission or there is no longer any transmission made during the following transmission periods E planned in the slots i, and a new unoccupied slot j is chosen. The above operations are repeated on slot j and if a transmission is received from another moving body, the transmission is once again prohibited or no longer made during subsequent transmission periods planned in the slot j.
