<p>A method of congestion management in a wireless mesh network in which the CSMA/CA algorithm is used to access wireless medium, said network comprising a first station and at least one neighboring station able to communicate directly with the first station, comprises:—broadcasting (22) an announcement message by the first station to the at least one neighboring station when the first station experiences a congestion in its environment, said announcement message comprising a congestion level parameter,—activating (26) by the neighboring station, at reception of the announcement message, a congestion state in which the minimum size of the time window, called contention window, to access the medium before transmission of a message is strictly greater than the minimum size (CWmin) defined in absence of congestion, said minimum size in congestion state being defined as a function of the congestion level parameter.</p> |
