Ideal rate control algorithmThis class implements an 'ideal' rate control algorithm similar to RBAR in spirit (see A rate-adaptive MAC protocol for multihop wireless networks by G. Holland, N. Vaidya, and P. Bahl.): every station keeps track of the snr of every packet received and sends back this snr to the original transmitter by an out-of-band mechanism. Each transmitter keeps track of the last snr sent back by a receiver and uses it to pick a transmission mode based on a set of snr thresholds built from a target ber and transmission mode-specific snr/ber curves.

Attributes defined for this type:
-
BerThreshold: The maximum Bit Error Rate acceptable at any transmission mode
-
Set with class: ns3::DoubleValue
-
Underlying type: double -1.79769e+308:1.79769e+308
-
Initial value: 1e-05
-
Flags: construct write read
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.
-
MaxSsrc: The maximum number of retransmission attempts for an RTS. This value will not have any effect on some rate control algorithms.
-
MaxSlrc: The maximum number of retransmission attempts for a DATA packet. This value will not have any effect on some rate control algorithms.
-
RtsCtsThreshold: If the size of the data packet + LLC header + MAC header + FCS trailer is bigger than this value, we use an RTS/CTS handshake before sending the data, as per IEEE Std. 802.11-2007, Section 9.2.6. This value will not have any effect on some rate control algorithms.
-
FragmentationThreshold: If the size of the data packet + LLC header + MAC header + FCS trailer is biggerthan this value, we fragment it such that the size of the fragments are equal or smaller than this value, as per IEEE Std. 802.11-2007, Section 9.4. This value will not have any effect on some rate control algorithms.
-
NonUnicastMode: Wifi mode used for non-unicast transmissions.
-
Set with class: WifiModeValue
-
Underlying type: WifiMode
-
Initial value: Invalid-WifiMode
-
Flags: construct write read
No TraceSources defined for this type.
TraceSources defined in parent class ns3::WifiRemoteStationManager:
-
MacTxRtsFailed: The transmission of a RTS by the MAC layer has failed
-
MacTxDataFailed: The transmission of a data packet by the MAC layer has failed
-
MacTxFinalRtsFailed: The transmission of a RTS has exceeded the maximum number of attempts
-
MacTxFinalDataFailed: The transmission of a data packet has exceeded the maximum number of attempts
