Low-delay high-rate operation of 802.11ac WLAN downlink: Nonlinear controller analysis & design

In this paper we present a novel nonlinear control design for regulating the aggregation level in 802.11 WLANs so as to ensure robust low-delay operation at high data rates. The controller compensates system nonlinearities and can be used full range of WLAN operation. We develop an implementation use evaluate performance using both simulations hardware measurements.
