privatevirtual

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 RTS

void ns3::AparfWifiManager::DoReportRtsOk	(	WifiRemoteStation *	station,
		double	ctsSnr,
		WifiMode	ctsMode,
		double	rtsSnr
	)

privatevirtual

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
ctsSnr	the SNR of the CTS we received
ctsMode	the WifiMode the receiver used to send the CTS
rtsSnr	the SNR of the RTS we sent

	)

privatevirtual

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 sent the DATA to us
rxSnr	the SNR of the DATA we received
txMode	the WifiMode the sender used to send the DATA

bool ns3::AparfWifiManager::IsLowLatency ( void ) const

privatevirtual

Returns: whether this manager is a manager designed to work in low-latency environments.

Note: In this context, low vs high latency is defined in IEEE 802.11 Rate Adaptation: A Practical Approach, by M. Lacage, M.H. Manshaei, and T. Turletti.

void ns3::AparfWifiManager::SetupPhy ( Ptr< WifiPhy > phy )

virtual

Set up PHY associated with this device since it is the object that knows the full set of transmit rates that are supported.
