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
  • 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.

No TraceSources are defined for this type.

bool  normally 
)
privatevirtual
Parameters
stationthe station that we need to communicate
packetthe packet to send
normallyindicates 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 packet before sending it, false otherwise.

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

Reimplemented from ns3::WifiRemoteStationManager.
