Detailed Description

an implementation of the AARF-CD algorithm

This algorithm was first described in "Efficient Collision Detection for Auto Rate Fallback Algorithm". The implementation available here was done by Federico Maguolo for a very early development version of ns-3. Federico died before merging this work in ns-3 itself so his code was ported to ns-3 later without his supervision.

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.

◆ DoCreateStation()

WifiRemoteStation * ns3::AarfcdWifiManager::DoCreateStation ( void ) const

overrideprivatevirtual

Returns: a new station data structure

Implements ns3::WifiRemoteStationManager.

◆ DoGetDataTxVector()

WifiTxVector ns3::AarfcdWifiManager::DoGetDataTxVector ( WifiRemoteStation * station )

overrideprivatevirtual

Parameters

station the station that we need to communicate

Returns: the TXVECTOR to use to send a packet to the station

Note: This method is called before sending a unicast packet or a fragment of a unicast packet to decide which transmission mode to use.

Parameters

station the 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 AARF algorithm for RTS only by picking a single rate within the BasicRateSet.

◆ DoInitialize()

void ns3::AarfcdWifiManager::DoInitialize ( void )

overrideprivatevirtual

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.

◆ DoNeedRts()

bool ns3::AarfcdWifiManager::DoNeedRts	(	WifiRemoteStation *	station,
		uint32_t	size,
		bool	normally
	)

overrideprivatevirtual

Parameters

station	the station that we need to communicate
size	the size of the frame to send in bytes
normally	indicates whether the normal 802.11 RTS enable mechanism would request that the RTS is sent or not.

Returns: true if we want to use an RTS/CTS handshake for this frame before sending it, false otherwise.

Note: This method is called before a unicast packet is sent on the medium.

◆ DoReportDataFailed()

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

overrideprivatevirtual

It is important to realize that "recovery" mode starts after failure of the first transmission after a rate increase and ends at the first successful transmission.

Specifically, recovery mode transcends retransmissions boundaries. Fundamentally, ARF handles each data transmission independently, whether it is the initial transmission of a packet or the retransmission of a packet. The fundamental reason for this is that there is a backoff between each data transmission, be it an initial transmission or a retransmission.

Parameters

station the station that we failed to send Data

◆ DoReportDataOk()

void ns3::AarfcdWifiManager::DoReportDataOk	(	WifiRemoteStation *	station,
		double	ackSnr,
		WifiMode	ackMode,

		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
