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 modes and will error exit if the user tries to configure this RAA with a Wi-Fi MAC that supports 802.11n or higher.

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.

◆ DoInitialize()

void ns3::AparfWifiManager::DoInitialize ( void  )
privatevirtual

Initialize() implementation.

This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

Reimplemented from ns3::Object.

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
dataChannelWidththe channel width (in MHz) of the DATA we sent
dataNssthe number of spatial streams used to send the DATA
