The methods for managing access to a communication medium shared by a plurality of radio communication devices. The method of accessing a radio communication medium shared between a plurality of communication terminals. The method is based on a variant of the CSMA/CD access protocol. The method is based on monitoring of the medium and the emission of a token to request permission to emit. The terminals that receive this token then emit an acknowledgement intended to signal that the medium can be used, or a collision message if they receive a plurality of tokens simultaneously. In the latter case, the emitter retries its attempt to use the medium later on. |
