Detailed Description

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.

◆ Receive()

void ns3::ApWifiMac::Receive	(	Ptr< const WifiMpdu >	mpdu,

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

mpdu	the MPDU that has been received.
linkId	the ID of the given link

Parameters
