No TraceSources are defined for this type.

TraceSources defined in parent class ns3::RegularWifiMac

• TxOkHeader: The header of successfully transmitted packet
• TxErrHeader: The header of unsuccessfully transmitted packet

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.
• MacTxDrop: A packet has been dropped in the MAC layer before being queued for transmission.
• 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.

Member Function Documentation

void ns3::ApWifiMac::DeaggregateAmsduAndForward ( Ptr< Packet >  aggregatedPacket, const WifiMacHeader *  hdr  )

privatevirtual

This method is called to de-aggregate an A-MSDU and forward the constituent packets up the stack. We override the WifiMac version here because, as an AP, we also need to think about redistributing to other associated STAs.

Parameters

aggregatedPacket	the Packet containing the A-MSDU.
hdr	a pointer to the MAC header for aggregatedPacket.

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

virtual

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 channel access function determines that access is granted to this MAC.

Implements ns3::RegularWifiMac.

Here is the call graph for this function:

void ns3::ApWifiMac::Enqueue ( Ptr< const Packet >  packet, Mac48Address  to, Mac48Address  from  )

virtual

Parameters

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

The packet should be enqueued in a tx queue, and should be dequeued as soon as the channel access function determines that access is granted to this MAC. The extra parameter "from" allows this device to operate in a bridged mode, forwarding received frames without altering the source address.
