Detailed Description

A constant ack policy selector operating based on the values of its attributes.


Introspection did not find any typical Config paths.


Attributes

  • UseExplicitBar: Specify whether to send Block Ack Requests (if true) or use Implicit Block Ack Request ack policy (if false).
    • Set with class: BooleanValue
    • Underlying type: bool
    • Initial value: false
    • Flags: construct write read
  • BaThreshold: Immediate acknowledgment is requested upon transmission of a frame whose sequence number is distant at least BaThreshold multiplied by the transmit window size from the starting sequence number of the transmit window. Set to zero to request a response for every transmitted frame.
    • Set with class: ns3::DoubleValue
    • Underlying type: double 0:1
    • Initial value: 0
    • Flags: construct write read

No TraceSources are defined for this type.
Size of this type is 56 bytes (on a 64-bit architecture).

Member Function Documentation

◆ GetTypeId()

TypeId ns3::ConstantWifiAckPolicySelector::GetTypeId ( void  )
static

Get the type ID.

Returns
the object TypeId

◆ UpdateTxParams()

void ns3::ConstantWifiAckPolicySelector::UpdateTxParams ( Ptr< WifiPsdu psdu,
MacLowTransmissionParameters params 
)
virtual

Update the transmission parameters related to the acknowledgment policy for the given PSDU.

This method is typically called by the MPDU aggregator when trying to aggregate another MPDU to the current A-MPDU. In fact, the AckPolicySelector may switch to a different acknowledgment policy when a new MPDU is aggregated to an A-MPDU. Note that multi-TID A-MPDUs are currently not supported by this method.

Parameters
psduthe given PSDU.
paramsthe MacLow parameters to update.

Implements ns3::WifiAckPolicySelector.
