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.

Member Function Documentation

virtual double ns3::YansWifiPhy::CalculateSnr ( WifiMode  txMode,
double  ber 
) const [virtual]
Parameters:
txMode the transmission mode
ber the probability of bit error rate
Returns:
the minimum snr which is required to achieve the requested ber for the specified transmission mode. (W/W)

Implements ns3::WifiPhy.

virtual Time ns3::YansWifiPhy::CalculateTxDuration ( uint32_t  size,
WifiMode  payloadMode,
enum WifiPreamble  preamble 
) const [virtual]
Parameters:
size the number of bytes in the packet to send
payloadMode the transmission mode to use for this packet
preamble the type of preamble to use for this packet.
Returns:
the total amount of time this PHY will stay busy for the transmission of these bytes.

Implements ns3::WifiPhy.

virtual Time ns3::YansWifiPhy::GetDelayUntilIdle ( void   )  [virtual]
Returns:
the predicted delay until this PHY can become WifiPhy::IDLE.

The PHY will never become WifiPhy::IDLE _before_ the delay returned by this method but it could become really idle later.

Implements ns3::WifiPhy.

virtual WifiMode ns3::YansWifiPhy::GetMode ( uint32_t  mode  )  const [virtual]

The WifiPhy::GetNModes() and WifiPhy::GetMode() methods are used (e.g., by a WifiRemoteStationManager) to determine the set of transmission/reception modes that this WifiPhy(-derived class) can support - a set of WifiMode objects which we call the DeviceRateSet, and which is stored as WifiPhy::m_deviceRateSet.

It is important to note that the DeviceRateSet is a superset (not necessarily proper) of the OperationalRateSet (which is logically, if not actually, a property of the associated WifiRemoteStationManager), which itself is a superset (again, not necessarily proper) of the BSSBasicRateSet.

Parameters:
mode index in array of supported modes
Returns:
the mode whose index is specified.

WifiPhy::GetNModes()

Implements ns3::WifiPhy.

virtual uint32_t ns3::YansWifiPhy::GetNModes ( void   )  const [virtual]

The WifiPhy::GetNModes() and WifiPhy::GetMode() methods are used (e.g., by a WifiRemoteStationManager) to determine the set of transmission/reception modes that this WifiPhy(-derived class) can support - a set of WifiMode objects which we call the DeviceRateSet, and which is stored as WifiPhy::m_deviceRateSet.

It is important to note that the DeviceRateSet is a superset (not necessarily proper) of the OperationalRateSet (which is logically, if not actually, a property of the associated WifiRemoteStationManager), which itself is a superset (again, not necessarily proper) of the BSSBasicRateSet.

Returns:
the number of transmission modes supported by this PHY.

the amount of time since the current state has started.

Implements ns3::WifiPhy.

virtual void ns3::YansWifiPhy::SendPacket ( Ptr< const Packet >  packet,
WifiMode  mode,
enum WifiPreamble  preamble,
uint8_t  txPowerLevel 
) [virtual]
Parameters:
packet the packet to send
mode the transmission mode to use to send this packet
preamble the type of preamble to use to send this packet.
txPowerLevel a power level to use to send this packet. The real transmission power is calculated as txPowerMin + txPowerLevel * (txPowerMax - txPowerMin) / nTxLevels

Implements ns3::WifiPhy.

void ns3::YansWifiPhy::SetChannelNumber ( uint16_t  id  )  [virtual]

Set channel number.

Channel center frequency = Channel starting frequency + 5 MHz * (nch - 1)

where Starting channel frequency is standard-dependent, see SetStandard() as defined in IEEE 802.11-2007 17.3.8.3.2.

YansWifiPhy can switch among different channels. Basically, YansWifiPhy has a private attribute m_channelNumber that identifies the channel the PHY operates on. Channel switching cannot interrupt an ongoing transmission. When PHY is in TX state, the channel switching is postponed until the end of the current transmission. When the PHY is in RX state, the channel switching causes the drop of the synchronized packet.

Implements ns3::WifiPhy.

Parameters:
callback the callback to invoke upon erroneous packet reception.

virtual void ns3::YansWifiPhy::SetReceiveOkCallback ( WifiPhy::RxOkCallback  callback  )  [virtual]
Parameters:
callback the callback to invoke upon successful packet reception.
