Title (EN) COLLISION AVOIDANCE METHOD AND SYSTEM FOR WIRELESS COMMUNICATION SYSTEMS
(FR) PROCÉDÉ ET SYSTÈME D'ÉVITEMENT DE COLLISION DESTINÉS À DES SYSTÈMES DE COMMUNICATION SANS FIL
Abstract:
(EN) A collision avoidance method for a wireless network comprising a plurality of devices, the method comprises receiving, by a first device of the plurality of devices, a message from a second device of the plurality of devices, transmitting, by the first device, a busy signal in response to the receiving of at least part of the message from the second device, the transmitting of the busy signal being at least partly simultaneous with the receiving of the message, receiving, by at least one further device of the plurality of devices, the busy signal, and delaying, by the at least one further device and in response to the busy signal, transmission of at least one further message by the at least one further device.
(FR) La présente invention concerne un procédé d'évitement de collision destiné à un réseau sans fil consistant en une pluralité de dispositifs. Le procédé consiste à recevoir, par un premier dispositif de la pluralité de dispositifs, un message en provenance d'un second dispositif de la pluralité de dispositifs, transmettre, par le premier dispositif, un signal d'occupation en réponse à la réception d'au moins une partie du message en provenance du second dispositif, la transmission du signal d'occupation étant au moins en partie simultanée avec la réception du message, recevoir, par au moins un autre dispositif de la pluralité de dispositifs, le signal d'occupation et retarder, par le ou les autres dispositifs et en réponse au signal d'occupation, la transmission d'au moins un autre message par le ou les autres dispositifs.
