Wi-Fi AP state machine.

Handle association, dis-association and authentication, of STAs within an infrastructure BSS. By default, beacons are sent with PIFS access, zero backoff, and are generated roughly every 102.4 ms by default (configurable by an attribute) and with some jitter to de-synchronize beacon transmissions in multi-BSS scenarios.

void ns3::ApWifiMac::DoDispose ( )

Destructor implementation.

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

Subclasses are expected to implement their real destruction code in an overridden 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.

This method is overridden because its implementation depends on the type of station.

◆ Receive()

void ns3::ApWifiMac::Receive ( Ptr< const WifiMpdu > mpdu,
uint8_t linkId )
overrideprivatevirtual

This method acts as the MacRxMiddle receive callback and is invoked to notify us that a frame has been received on the given link.

The implementation is intended to capture logic that is going to be common to all (or most) derived classes. Specifically, handling of Block Ack management frames is dealt with here.

This method will need, however, to be overridden by derived classes so that they can perform their data handling before invoking the base version.

The given link may be undefined in some cases (e.g., in case of QoS Data frames received in the context of a Block Ack agreement – because the BlockAckManager does not have to record the link each buffered MPDU has been received on); in such a cases, the value of linkId should be WIFI_LINKID_UNDEFINED.

Parameters
mpduthe MPDU that has been received.
linkIdthe ID of the given link

The packet we sent was successfully received by the receiver (i.e.

we did not receive an Ack from the receiver). If the packet was an association response to the receiver, we record that the receiver is not associated with us yet.

◆ TxOk()

void ns3::ApWifiMac::TxOk ( Ptr< const WifiMpdu > mpdu)
private

The packet we sent was successfully received by the receiver (i.e.

we received an Ack from the receiver). If the packet was an association response to the receiver, we record that the receiver is now associated with us.

Parameters
mpduthe MPDU that we successfully sent

The STA is affiliated with an MLD. From Sec. 35.3.7.1.4 of 802.11be D3.0: When a link becomes enabled for a non-AP STA that is affiliated with a non-AP MLD after successful association with an AP MLD with (Re)Association Request/Response frames transmitted on another link [...], the power management mode of the non-AP STA, immediately after the acknowledgement of the (Re)Association Response frame [...], is power save mode, and its power state is doze.

Thus, STAs operating on all the links but the link used to establish association transition to power save mode.

◆ UpdateShortPreambleEnabled()

void ns3::ApWifiMac::UpdateShortPreambleEnabled ( uint8_t linkId)
private

Update whether short preamble should be enabled or not in the BSS corresponding to the given link.

Typically, short preamble is enabled only when the AP and all associated stations support short PHY preamble. Otherwise, it is disabled.

Parameters
linkIdthe ID of the given link

◆ UpdateShortSlotTimeEnabled()

void ns3::ApWifiMac::UpdateShortSlotTimeEnabled ( uint8_t linkId)
private

Update whether short slot time should be enabled or not in the BSS corresponding to the given link.

Typically, short slot time is enabled only when there is no non-ERP station associated to the AP, and that short slot time is supported by the AP and by all other ERP stations that are associated to the AP. Otherwise, it is disabled.

Parameters
linkIdthe ID of the given link
