Detailed Description

802.11 PHY layer model

This PHY implements a model of 802.11a.


The model implemented here is based on the model described in "Yet Another Network Simulator", (http://cutebugs.net/files/wns2-yans.pdf).

This PHY model depends on a channel loss and delay model as provided by the ns3::PropagationLossModel and ns3::PropagationDelayModel classes, both of which are members of the ns3::YansWifiChannel class.

Config Paths

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

  • "/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phy/$ns3::YansWifiPhy"
  • "/NodeList/[i]/DeviceList/[i]/$ns3::WaveNetDevice/PhyEntities/[i]/$ns3::YansWifiPhy"

No Attributes are defined for this type.

Attributes defined in parent class ns3::WifiPhy

  • Frequency: The center frequency (MHz) of the operating channel. If the operating channel for this object has not been set yet, the value of this attribute is saved and will be used, along with the channel number and width configured via other attributes, to set the operating channel when the standard and band are configured. The default value of this attribute is 0, which means unspecified center frequency. Note that if center frequency and channel number are both 0 when the standard and band are configured, a default channel (of the configured width, if any, or the default width for the current standard and band, otherwise) is set. If the operating channel for this object has been already set, the specified center frequency must uniquely identify a channel in the band being used.
    • Set with class: ns3::UintegerValue
    • Underlying type: uint16_t 0:65535
    • Initial value: 0
    • Flags: construct write read
  • ChannelNumber: The channel number of the operating channel. If the operating channel for this object has not been set yet, the value of this attribute is saved and will be used, along with the center frequency and width configured via other attributes, to set the operating channel when the standard and band are configured. The default value of this attribute is 0, which means unspecified channel number. Note that if center frequency and channel number are both 0 when the standard and band are configured, a default channel (of the configured width, if any, or the default width for the current standard and band, otherwise) is set. If the operating channel for this object has been already set, the specified channel number must uniquely identify a channel in the band being used.
    • Set with class: ns3::UintegerValue
    • Underlying type: uint8_t 0:233
    • Initial value: 0
    • Flags: construct write read
  • ChannelWidth: The width in MHz of the operating channel (5, 10, 20, 22, 40, 80 or 160). If the operating channel for this object has not been set yet, the value of this attribute is saved and will be used, along with the center frequency and channel number configured via other attributes, to set the operating channel when the standard and band are configured. The default value of this attribute is 0, which means unspecified channel width. Note that if center frequency and channel number are both 0 when the standard and band are configured, a default channel (of the configured width, if any, or the default width for the current standard and band, otherwise) is set. Do not set this attribute when the standard and band of this object have been already configured, because it cannot uniquely identify a channel in the band being used.
    • Set with class: ns3::UintegerValue
    • Underlying type: uint16_t 5:160
    • Initial value: 0
    • Flags: construct write read
  • Primary20MHzIndex: The index of the primary 20 MHz channel within the operating channel (0 indicates the 20 MHz subchannel with the lowest center frequency). This attribute is only valid if the width of the operating channel is a multiple of 20 MHz.
    • Set with class: ns3::UintegerValue
    • Underlying type: uint8_t 0:7
    • Initial value: 0
    • Flags: construct write
  • RxSensitivity: The energy of a received signal should be higher than this threshold (dBm) for the PHY to detect the signal. This threshold refers to a width of 20 MHz and will be scaled to match the width of the received signal.
    • Set with class: ns3::DoubleValue
    • Underlying type: double -1.79769e+308:1.79769e+308
    • Initial value: -101
    • Flags: construct write read
  • CcaEdThreshold: The energy of a non Wi-Fi received signal should be higher than this threshold (dBm) to allow the PHY layer to declare CCA BUSY state. This check is performed on the 20 MHz primary channel only.
    • Set with class: ns3::DoubleValue
    • Underlying type: double -1.79769e+308:1.79769e+308
    • Initial value: -62
    • Flags: construct write read

◆ DoDispose()

void ns3::YansWifiPhy::DoDispose ( void  )
overrideprotectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::WifiPhy.

Return the Channel this WifiPhy is connected to.

Returns

◆ GetGuardBandwidth()

uint16_t ns3::YansWifiPhy::GetGuardBandwidth ( uint16_t  currentChannelWidth) const
overridevirtual
Parameters
currentChannelWidthchannel width of the current transmission (MHz)
Returns
the width of the guard band (MHz)

Note: in order to properly model out of band transmissions for OFDM, the guard band has been configured so as to expand the modeled spectrum up to the outermost referenced point in "Transmit spectrum mask" sections' PSDs of each PHY specification of 802.11-2016 standard. It thus ultimately corresponds to the current channel bandwidth (which can be different from devices max channel width).

This method is only relevant for SpectrumWifiPhy.
