  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).

CanForwardPacketsTo()

bool ns3::AdhocWifiMac::CanForwardPacketsTo ( Mac48Address  to ) const

overridevirtual

Return true if packets can be forwarded to the given destination, false otherwise.

Parameters

to	the address to which the packet should be sent

Returns

whether packets can be forwarded to the given destination

Implements ns3::WifiMac.

Definition at line 63 of file adhoc-wifi-mac.cc.

Enqueue()

void ns3::AdhocWifiMac::Enqueue ( Ptr< Packet >  packet, Mac48Address  to  )

overridevirtual

Parameters

packet	the packet to send.
to	the address to which the packet should be sent.

The packet should be enqueued in a TX queue, and should be dequeued as soon as the DCF function determines that access it granted to this MAC.

Implements ns3::WifiMac.

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

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