A binomial rate control for a media aware Access Point

Multimedia communications over Wireless Local Area Networks like hotspots, are a challenging issue due to the best-effort nature of Internet communications. In a previous work we introduced a Dual-Queue Rate-Controlled mechanism for Access Points (DRAP) in a Hotspot scenario. DRAP has shown to provide some Quality of Service (QoS) guarantees to audio and video traffic flows in the presence of TCP background traffic. In this paper we present an enhancement for DRAP based on a binomial rate control algorithm. We call this enhancement a Binomial DRAP (B-DRAP). Our simulation results show that B-DRAP could be an alternative to provide soft QoS guarantees for multimedia communications.
