Detailed Description

Basic MAC of mesh point Wi-Fi interface.

Its function is extendable through plugins mechanism.

Now only three output queues are used:

  • beacons (PIFS and no backoff),
  • background traffic,
  • management and priority traffic.

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
  • DroppedMpdu: An MPDU that was dropped for the given reason (see WifiMacDropReason).
    Callback signature: ns3::WifiMac::DroppedMpduCallback
  • 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
  • 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
  • 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.
    Callback signature: ns3::WifiMac::MpduResponseTimeoutCallback
  • NAckedMpdu: An MPDU that was negatively acknowledged via a Block Ack.
    Callback signature: ns3::WifiMpdu::TracedCallback
  • 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.
    Callback signature: ns3::WifiMac::PsduMapResponseTimeoutCallback
  • 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
