Abstract Real-time broadcast and multicast based packet transmissions/services over a wireless, local area networks (WLAN) may be improved by reducing the interference across neighboring access points (APs) while minimally impacting the performance of unicast transmissions/services. Minimal impact is assured by scheduling the transmission of multicast packet flows such that the duration of the time period required to transmit such flows is also minimized. One type of method provides a constant approximation of an optimal time period/schedule while another provides a logarithmic approximation of an optimal time L'invention concerne des transmissions par paquets/services à base de diffusion et de multidiffusion en temps réel sur des réseaux locaux sans fil (WLAN) améliorer en réduisant l'interférence de points d'accès voisins (AP) tout en ayant un impact minimum sur la performance de transmissions/services d'unidiffusion. L'impact minimum est garanti en planifiant la transmission de flux de paquets de multidiffusion de telle sorte que la durée nécessaire pour transmettre de tels flux est également reduite. Un type de procédé fournit une approximation constante de la période de temps/planification optimum, tandis qu'un autre fournit une approximation logarithmique du temps optimum.
