Detailed Description

APARF Power and rate control algorithm.

This class implements the High Performance power and rate control algorithm described in Dynamic data rate and transmit power adjustment in IEEE 802.11 wireless LANs by Chevillat, P.; Jelitto, J. and Truong, H. L. in International Journal of Wireless Information Networks, Springer, 2005, 12, 123-145. http://www.cs.mun.ca/~yzchen/papers/papers/rate_adaptation/80211_dynamic_rate_power_adjustment_chevillat_j2005.pdf

This RAA does not support HT, VHT nor HE modes and will error exit if the user tries to configure this RAA with a Wi-Fi MAC that has VhtSupported, HtSupported or HeSupported set.

WifiTxVector ns3::AparfWifiManager::DoGetRtsTxVector ( WifiRemoteStation station)
privatevirtual
Parameters
stationthe station that we need to communicate
Returns
the transmission mode to use to send an rts to the station

Note: This method is called before sending an rts to a station to decide which transmission mode to use for the rts.

Todo:
we could/should implement the Arf algorithm for RTS only by picking a single rate within the BasicRateSet.

This method is a pure virtual method that must be implemented by the sub-class.

This allows different types of WifiRemoteStationManager to respond differently,

Parameters
stationthe station that we successfully sent RTS
ackSnrthe SNR of the ACK we received
ackModethe WifiMode the receiver used to send the ACK
dataSnrthe SNR of the DATA we sent
