TypeId ns3::ConstantRateWifiManager::GetTypeId ( void )

static

This method returns the TypeId associated to ns3::ConstantRateWifiManager.

This object is accessible through the following paths with Config::Set and Config::Connect:

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

Attributes defined for this type:

DataMode: The transmission mode to use for every data packet transmission
- Set with class: WifiModeValue
- Underlying type: WifiMode
- Initial value: OfdmRate6Mbps
- Flags: construct write read
ControlMode: The transmission mode to use for every control packet transmission.
- Set with class: WifiModeValue
- Underlying type: WifiMode
- Initial value: OfdmRate6Mbps
- 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.
- 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

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
