Config Paths

ns3::WifiRemoteStationManager is accessible through the following paths with Config::Set and Config::Connect:

• /NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/RemoteStationManager

Attributes

• 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 an RTS. This value will not have any effect on some rate control algorithms.
  • Set with class: ns3::UintegerValue
  • Underlying type: uint32_t 0:4294967295
  • Initial value: 7
  • Flags: construct write read
• MaxSlrc: The maximum number of retransmission attempts for a DATA packet. This value will not have any effect on some rate control algorithms.
  • Set with class: ns3::UintegerValue
  • Underlying type: uint32_t 0:4294967295
  • Initial value: 7
  • Flags: construct write read
• 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.
  • Set with class: ns3::UintegerValue
  • Underlying type: uint32_t 0:4294967295
  • Initial value: 2346
  • Flags: construct write read
• 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.
  • Set with class: ns3::UintegerValue
  • Underlying type: uint32_t 0:4294967295
  • Initial value: 2346
  • Flags: construct write read
• NonUnicastMode: Wifi mode used for non-unicast transmissions.
  • Set with class: WifiModeValue
  • Underlying type: WifiMode
  • Initial value: Invalid-WifiMode
  • Flags: construct write read
• DefaultTxPowerLevel: Default power level to be used for transmissions. This is the power level that is used by all those WifiManagers that do notimplement TX power control.
  • Set with class: ns3::UintegerValue
  • Underlying type: uint8_t 0:255
  • Initial value: 0
  • Flags: construct write read

TraceSources

• 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

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

The standard has relatively unambiguous rules for selecting a control response rate (the below is quoted from IEEE 802.11-2007, Section 9.6):

To allow the transmitting STA to calculate the contents of the Duration/ID field, a STA responding to a received frame shall transmit its Control Response frame (either CTS or ACK), other than the BlockAck control frame, at the highest rate in the BSSBasicRateSet parameter that is less than or equal to the rate of the immediately previous frame in the frame exchange sequence (as defined in 9.12) and that is of the same modulation class (see 9.6.1) as the received frame...

If no suitable basic rate was found, we search the mandatory rates. The standard (IEEE 802.11-2007, Section 9.6) says:

...If no rate contained in the BSSBasicRateSet parameter meets these conditions, then the control frame sent in response to a received frame shall be transmitted at the highest mandatory rate of the PHY that is less than or equal to the rate of the received frame, and that is of the same modulation class as the received frame. In addition, the Control Response frame shall be sent using the same PHY options as the received frame, unless they conflict with the requirement to use the BSSBasicRateSet parameter.

Todo:

Note that we're ignoring the last sentence for now, because there is not yet any manipulation here of PHY options.

If we still haven't found a suitable rate for the response then someone has messed up the simulation config. This probably means that the WifiPhyStandard is not set correctly, or that a rate that is not supported by the PHY has been explicitly requested in a WifiRemoteStationManager (or descendant) configuration.

Either way, it is serious - we can either disobey the standard or fail, and I have chosen to do the latter...
