Abstract
The invention relates to a method and device for sending data over a channel of a communication medium comprising a plurality of channels and which can be accessed by a plurality of nodes. Each node using a medium access mechanism with collision avoidance based on a computation of backoff values corresponding to a number of time-slots a node waits before accessing the communication medium. The method comprising the following steps performed by a first node of the plurality of nodes upon the reception of a trigger frame: obtaining a backoff counter value computed by the first node; selecting a channel among the plurality of channels based on the obtained backoff counter; and sending data on the selected channel by the first node.
