Detailed Description

PARF Rate control algorithm.

This class implements the PARF algorithm as described in Self-management in chaotic wireless deployments, by Akella, A.; Judd, G.; Seshan, S. and Steenkiste, P. in Wireless Networks, Kluwer Academic Publishers, 2007, 13, 737-755 http://www.cs.odu.edu/~nadeem/classes/cs795-WNS-S13/papers/enter-006.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.

Attributes defined in parent class ns3::WifiRemoteStationManager

IsLowLatency: If true, we attempt to modelize a so-called low-latency device: a device where decisions about tx parameters can be made on a per-packet basis and feedback about the transmission of each packet is obtained before sending the next. Otherwise, we modelize a high-latency device, that is a device where we cannot update our decision about tx parameters after every packet transmission.
- Set with class: BooleanValue
- Underlying type: bool
- Flags: read
MaxSsrc: The maximum number of retransmission attempts for any packet with size <= RtsCtsThreshold. This value will not have any effect on some rate control algorithms.

- Initial value: 7
- Flags: construct write
MaxSlrc: The maximum number of retransmission attempts for any packet with size > RtsCtsThreshold. This value will not have any effect on some rate control algorithms.

- Initial value: 65535
- Flags: construct write
FragmentationThreshold: If the size of the PSDU is bigger than this value, we fragment it such that the size of the fragments are equal or smaller. This value does not apply when it is carried in an A-MPDU. This value will not have any effect on some rate control algorithms.

WifiTxVector ns3::ParfWifiManager::DoGetRtsTxVector ( WifiRemoteStation * station )

privatevirtual

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

◆ DoReportDataFailed()

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

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 DATA

	)

privatevirtual

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