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.
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).

ns3::WifiMacQueue

Expired: MPDU dropped because its lifetime expired.

ns3::WifiPhy

MonitorSnifferRx: Trace source simulating a wifi device in monitor mode sniffing all received frames
MonitorSnifferTx: Trace source simulating the capability of a wifi device in monitor mode to sniff all frames being transmitted
PhyRxBegin: Trace source indicating a packet has begun being received from the channel medium by the device
PhyRxDrop: Trace source indicating a packet has been dropped by the device during reception
PhyRxEnd: Trace source indicating a packet has been completely received from the channel medium by the device
PhyRxMacHeaderEnd: Trace source indicating the MAC header of an MPDU has been completely received.
PhyRxPayloadBegin: Trace source indicating the reception of the payload of a PPDU has begun
PhyRxPpduDrop: Trace source indicating a ppdu has been dropped by the device during reception
PhyTxBegin: Trace source indicating a packet has begun transmitting over the medium; the packet holds a single MPDU even if the MPDU is transmitted within an A-MPDU (in which case this trace fires for each MPDU in the A-MPDU).
PhyTxDrop: Trace source indicating a packet has been dropped by the device during transmission
PhyTxEnd: Trace source indicating a packet has been completely transmitted over the channel.
PhyTxPsduBegin: Trace source indicating a PSDU has begun transmitting over the channel medium; this trace returns a WifiConstPsduMap with a single element (in the case of SU PPDU) or multiple elements (in the case of MU PPDU)
SignalTransmission: Trace start of signal transmission

MacTxDataFailed: The transmission of a data packet by the MAC layer has failed
MacTxFinalDataFailed: The transmission of a data packet has exceeded the maximum number of attempts
MacTxFinalRtsFailed: The transmission of a RTS has exceeded the maximum number of attempts
