Claim Text:
1. A method for establishing a first and second association between a main node and respectively a first and second wireless node, the first association associating a first virtual access point of the main node and the first node, the first virtual access point transmitting to the first node first beacon frames comprising a first item of information representative of said first association, the first virtual access point being identified by a services set identifier wherein, when the main node receives from the node a request for the establishment of the second association, the method comprises, at the level of a controller: creating a second virtual access point of the main node transmitting to the second node second beacon frames comprising a second item of information representative of said second association, said second virtual access point being identified by the services set identifier; initializing a total data transmission bit rate practiced by the first and second node linked to the physical modulation used by respectively the first and second node in the first and second association, initializing a first and second data transmission bit rate required by respectively the first and second node transmitted in the first and second association, and initializing a frame duration; determining a first and a second temporal interval during which respectively the first node and the first virtual access point on one hand, the second node and the second virtual access point are prohibited from sending the second temporal interval having a frame duration that is proportional to the frame duration and proportional to the first data transmission bit rate required by the first node relative to the total data transmission bit rate, and the first temporal interval having a duration that is proportional to the frame duration and proportional to the second data transmission bit rate required by the second node relative to the total data transmission bit rate; establishing of the second association between the second node and the second virtual access point; and transmitting, to the first node at least one item of quiet information representative of a prohibition to transmit during the first temporal interval, and to the second node at least one item of quiet information representative of a prohibition to transmit during the second temporal interval.
