Detailed Description

Ideal rate control algorithm.

This 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.
- Set with class: BooleanValue
- Underlying type: bool
- Initial value: true
- Flags: construct write 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 a data packet is bigger than this value, we use an RTS/CTS handshake before sending the data. 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: 1500
- Flags: construct write read
FragmentationThreshold: If a data packet is bigger than this value, we fragment it such that the size of the fragments are equal or smaller than this value. 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: 1500
- 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
