  • VO_Txop: Queue that manages packets belonging to AC_VO access class.

No TraceSources are defined for this type.

TraceSources defined in parent class ns3::WifiMac

  • AckedMpdu: An MPDU that was successfully acknowledged, via either a Normal Ack or a Block Ack.
    • Callback signature: ns3::WifiMpdu::TracedCallback
    • Support level: SUPPORTED
  • DroppedMpdu: An MPDU that was dropped for the given reason (see WifiMacDropReason).
  • IcfDropReason: An ICF is dropped by an EMLSR client for the given reason on the link with the given ID. This trace source is actually fed by the EHT Frame Exchange Manager through the m_icfDropCallback member variable.
  • 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.
  • 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.
  • MacRxDrop: A packet has been dropped in the MAC layer after it has been passed up from the physical layer.
  • MacTx: A packet has been received by the WifiNetDevice and is about to be enqueued; it has a LlcSnapHeader prepended but not yet a WifiMacHeader.
  • 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.
  • 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, when all CTS frames are missing after an MU-RTS, or when a Normal Ack is missing after an MPDU or after a DL MU PPDU acknowledged in SU format.
  • NAckedMpdu: An MPDU that was negatively acknowledged via a Block Ack.
    • Callback signature: ns3::WifiMpdu::TracedCallback
    • Support level: SUPPORTED
  • 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.
  • 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).

tothe address to which the packet should be sent
Returns
whether packets can be forwarded to the given destination

Parameters
mpduthe MPDU to send.
tothe address to which the packet should be sent.
fromthe address from which the packet should be sent.

Subclasses need to implement this method to finalize the MAC header of the MPDU (MAC addresses and ToDS/FromDS flags) and enqueue the MPDU in a TX queue.

◆ Receive()

void ns3::AdhocWifiMac::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
