TraceSources

TraceSources defined in parent class ns3::WifiMac

  • MacTx: A packet has been received from higher layers and is being processed in preparation for queueing for transmission.
    Callback signature: ns3::Packet::TracedCallback
  • MacTxDrop: A packet has been dropped in the MAC layer before being queued for transmission. This trace source is fired, e.g., when an AP's MAC receives from the upper layer a packet destined to a station that is not associated with the AP or a STA's MAC receives a packet from the upper layer while it is not associated with any AP.
    Callback signature: ns3::Packet::TracedCallback
  • MacPromiscRx: A packet has been received by this device, has been passed up from the physical layer and is being forwarded up the local protocol stack. This is a promiscuous trace.
    Callback signature: ns3::Packet::TracedCallback
  • MacRx: A packet has been received by this device, has been passed up from the physical layer and is being forwarded up the local protocol stack. This is a non-promiscuous trace.
    Callback signature: ns3::Packet::TracedCallback
  • MacRxDrop: A packet has been dropped in the MAC layer after it has been passed up from the physical layer.
    Callback signature: ns3::Packet::TracedCallback

  • NAckedMpdu: An MPDU that was negatively acknowledged via a Block Ack.
    Callback signature: ns3::WifiMacQueueItem::TracedCallback
  • DroppedMpdu: An MPDU that was dropped for the given reason (see WifiMacDropReason).
    Callback signature: ns3::WifiMac::DroppedMpduCallback
  • MpduResponseTimeout: An MPDU whose response was not received before the timeout, along with an identifier of the type of timeout (see WifiTxTimer::Reason) and the TXVECTOR used to transmit the MPDU. This trace source is fired when a CTS is missing after an RTS or a Normal Ack is missing after an MPDU or after a DL MU PPDU acknowledged in SU format.
    Callback signature: ns3::WifiMac::MpduResponseTimeoutCallback
  • PsduResponseTimeout: A PSDU whose response was not received before the timeout, along with an identifier of the type of timeout (see WifiTxTimer::Reason) and the TXVECTOR used to transmit the PSDU. This trace source is fired when a BlockAck is missing after an A-MPDU, a BlockAckReq (possibly in the context of the acknowledgment of a DL MU PPDU in SU format) or a TB PPDU (in the latter case the missing BlockAck is a Multi-STA BlockAck).
    Callback signature: ns3::WifiMac::PsduResponseTimeoutCallback
  • PsduMapResponseTimeout: A PSDU map for which not all the responses were received before the timeout, along with an identifier of the type of timeout (see WifiTxTimer::Reason), the set of MAC addresses of the stations that did not respond and the total number of stations that had to respond. This trace source is fired when not all the addressed stations responded to an MU-BAR Trigger frame (either sent as a SU frame or aggregated to PSDUs in the DL MU PPDU), a Basic Trigger Frame or a BSRP Trigger Frame.

Destructor implementation.

◆ Receive()

void ns3::ApWifiMac::Receive ( Ptr< WifiMacQueueItem 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
mpduthe MPDU that has been received.
linkIdthe ID of the given link
