La technique de transmission radio Full-Duplex est une caract�ristique importante de la couche physique de la nouvelle norme IEEE 802.11ax visant � promouvoir l'utilisation du WiFi 6, �galement appel� WLAN � haute efficacit�. Gr�ce � cette technique sans pr�c�dent, un �metteur WiFi peut transmettre et recevoir des donn�es simultan�ment en utilisant le m�me canal radio, ce qui double la capacit� du r�seau et l'efficacit� spectrale. Cependant, de nombreux d�fis li�s � la couche MAC (notamment les configurations Full-Duplex, les relations cach�es, le d�s�quilibre entre les flux de donn�es et l'overhead) doivent �tre relev�s pour tirer pleinement parti de cette technique. Dans cet ouvrage, nous nous int�ressons � la conception, � la mise en oeuvre et � l'�valuation d'un nouveau protocole MAC Full-Duplex en relevant les d�fis inh�rents au contr�le des communications radio Full-Duplex. En cons�quence, un protocole de contr�le efficace et coordonn� est propos�, dont le principe de base est d'�changer toutes les informations de contr�le pertinentes et de transmettre les donn�es sans perte ni retard inutile. L'�valuation des performances du protocole propos� montre que les r�sultats obtenus sont les meilleurs, en particulier lorsque le r�seau est dense ou que le trafic en provenance du point d'acc�s est important.
