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 for system nonlinearities and so can be used for the full range of WLAN operation. We develop an im...

Description
Summary: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 for system nonlinearities and so can be used for the full range of WLAN operation. We develop an implementation of the nonlinear control design and use this to evaluate performance using both simulations and hardware measurements.
