Abstract
Although extensive studies have been carried out on the provision of multicast services in wireless local area networks (WLANs), most of them do not consider the use of directional antennasIn particular, rate adaptation and fairness issues among sectors in directional multicast are not well-studied topicsIn this paper, a fair rate adaptation scheme (FRAS) that seeks to determine appropriate transmission rates that maintain fairness among sectors and accommodate as many multicast devices as possible is proposedExtensive simulation results show that FRAS outperforms the equal-rate scheme in terms of the number of devices that receive multicast framesFurthermore, FRAS can improve the fairness performance as compared with the heavy-sector first scheme.
