◆ DoReportDataFailed()

void ns3::ConstantRateWifiManager::DoReportDataFailed ( WifiRemoteStation * station )

overrideprivatevirtual

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

station the station that we failed to send DATA

Implements ns3::WifiRemoteStationManager.

◆ DoReportDataOk()

void ns3::ConstantRateWifiManager::DoReportDataOk	(	WifiRemoteStation *	station,
		double	ackSnr,
		WifiMode	ackMode,
		double	dataSnr,
		uint16_t	dataChannelWidth,
		uint8_t	dataNss
	)

overrideprivatevirtual

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

station	the station that we successfully sent RTS
ackSnr	the SNR of the ACK we received
ackMode	the WifiMode the receiver used to send the ACK
dataSnr	the SNR of the DATA we sent
dataChannelWidth	the channel width (in MHz) of the DATA we sent
dataNss	the number of spatial streams used to send the DATA
