Detailed Description

Config Paths

ns3::StaWifiMac is accessible through the following paths with Config::Set and Config::Connect:

  • /NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Mac/$ns3::RegularWifiMac/$ns3::StaWifiMac
  • /NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Mac/$ns3::StaWifiMac

Attributes

  • ProbeRequestTimeout: The interval between two consecutive probe request attempts.
    • Set with class: TimeValue
    • Underlying type: Time
    • Initial value: +50000000.0ns
    • Flags: construct write read

TraceSources

  • Assoc: Associated with an access point.
  • DeAssoc: Association with an access point lost.

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::StaWifiMac::Enqueue ( Ptr< const Packet packet,
Mac48Address  to 
)
virtual
Parameters
packetthe packet to send.
tothe 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.

void ns3::StaWifiMac::Receive ( Ptr< Packet packet,
const WifiMacHeader hdr 
)
privatevirtual

This method acts as the MacRxMiddle receive callback and is invoked to notify us that a frame has been received. The implementation is intended to capture logic that is going to be common to all (or most) derived classes. Specifically, handling of Block Ack managment frames is dealt with here.

This method will need, however, to be overriden by derived classes so that they can perform their data handling before invoking the base version.

Parameters
packetthe packet that has been received.
hdra pointer to the MAC header of the received frame.

Reimplemented from ns3::RegularWifiMac.
