Detailed Description

A 802.11 Channel.

This channel subclass can be used to connect together a set of ns3::WifiNetDevice network interfaces. A WifiChannel contains a ns3::PropagationLossModel and a ns3::PropagationDelayModel which can be overriden by the WifiChannel::SetPropagationLossModel and the WifiChannel::SetPropagationDelayModel methods. By default, no propagation models are set.

void ns3::WifiChannel::Add	(	Ptr< NetDevice >	device,
		Ptr< WifiPhy >	phy
	)

Parameters:

	device	the device to add to the list of connected devices.
	phy	the physical layer which will receive packets on behalf of the device.

This method should not be invoked by normal users. It is currently invoked only from WifiPhy::SetChannel.

virtual Ptr<NetDevice> ns3::WifiChannel::GetDevice

(

uint32_t

i

)

const [virtual]

Parameters:

i

index of the requested network interface.

Returns:

the requested network interfaces connected to this channel.

Overriden from the NetDevice base class. Indexes start at 0 and end at n-1.

Implements ns3::Channel.

virtual uint32_t ns3::WifiChannel::GetNDevices

(

void

)

const [virtual]

Returns:

the number of network interfaces connected to this channel.

Overriden from the NetDevice base class.

Implements ns3::Channel.

void

)

[static]

This method returns the TypeId associated to ns3::WifiChannel.

This object is accessible through the following paths with Config::Set and Config::Connect:

• /NodeList/[i]/DeviceList/[i]/$ns3WifiNetDevice/Channel

Attributes defined for this type:

• PropagationLossModel: A pointer to the propagation loss model attached to this channel.
  • Set with class: ns3::PointerValue
  • Underlying type: ns3::Ptr< ns3::PropagationLossModel >
  • Initial value: 0
  • Flags: construct write read
• PropagationDelayModel: A pointer to the propagation delay model attached to this channel.
  • Set with class: ns3::PointerValue
  • Underlying type: ns3::Ptr< ns3::PropagationDelayModel >
  • Initial value: 0
  • Flags: construct write read

No TraceSources defined for this type.

Reimplemented from ns3::Channel.

void ns3::WifiChannel::Send	(	Ptr< WifiPhy >	sender,
		Ptr< const Packet >	packet,
		double	txPowerDbm,
		WifiMode	wifiMode,
		WifiPreamble	preamble
	)			const

Parameters:

	sender	the device from which the packet is originating.
	packet	the packet to send
	txPowerDbm	the tx power associated to the packet
	wifiMode	the tx mode associated to the packet
	preamble	the preamble associated to the packet

This method should not be invoked by normal users. It is currently invoked only from WifiPhy::Send.

)

Parameters:

delay

the new propagation delay model.

void ns3::WifiChannel::SetPropagationLossModel

(

Ptr< PropagationLossModel >

loss

)

Parameters:

loss
