Abstract
A method for multiple access to a frequency band of a communication channel of a communication network with carrier sense and collision avoidance, the said frequency band being divided into a set of sub-bands includes, at a source node, detecting the availability of the communication channel and transmitting to a destination node a request message for authorization to send data on the communication channel sent over one or more sub-bands, and, at the destination node, detecting simultaneous request messages for authorization to send data on the communication channel transmitted by a plurality of source nodes over a plurality of sub-bands. A message is transmitted authorizing the sending of data on the communication channel by at least one source node among the said plurality of source nodes.
