Abstract

The 802.11e and subsequently the 802.11n amendments
brought Quality of Service (QoS) into the Wireless Local
Area Network (WLAN) arena, in order to provide higher access
priority to certain types of traffic such as video and voice.
Unfortunately these improvements are not enough, since in very
dense and highly loaded network conditions they can provide
more harm than benefits, by making the lower priority traffic
starve and increasing the average collision rate. This lack of
performance in the Medium Access Control (MAC) layer is where
we focused our work. We propose a solution that avoids the
starvation of the lowest priority Access Categories (AC), taking
into account the priority defined by the 802.11e amendment and
at negligible or extremely low cost for the high priority ones.
Simulation results presented in this paper prove the effectiveness
of the method by showing delay improvements up to 92% in
overcrowded and overloaded networks.
