Detailed Description

a channel to interconnect ns3::YansWifiPhy objects.

This class is expected to be used in tandem with the ns3::YansWifiPhy class and supports an ns3::PropagationLossModel and an ns3::PropagationDelayModel. By default, no propagation models are set; it is the caller's responsibility to set them before using the channel.

Config Paths

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

"/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phy/Channel/$ns3::YansWifiChannel"
"/NodeList/[i]/DeviceList/[i]/$ns3::WifiNetDevice/Phys/[i]/Channel/$ns3::YansWifiChannel"
"/ChannelList/[i]/$ns3::YansWifiChannel"

Attributes

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: constructwriteread
- Support level: SUPPORTED
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: constructwriteread
- Support level: SUPPORTED

Attributes defined in parent class ns3::Channel

Id: The id (unique integer) of this Channel.

◆ Receive()

void ns3::YansWifiChannel::Receive	(	Ptr< YansWifiPhy >	receiver,
		Ptr< const WifiPpdu >	ppdu,
		dBm_u	txPower )

staticprivate

This method is scheduled by Send for each associated YansWifiPhy.

The method then calls the corresponding YansWifiPhy that the first bit of the PPDU has arrived.

Parameters

receiver	the device to which the packet is destined
ppdu	the PPDU being sent
txPower	the TX power associated to the packet being sent

◆ Send()

void ns3::YansWifiChannel::Send	(	Ptr< YansWifiPhy >	sender,

		dBm_u	txPower ) const

Parameters

sender	the PHY object from which the packet is originating.
ppdu	the PPDU to send
txPower	the TX power associated to the packet

This method should not be invoked by normal users. It is currently invoked only from YansWifiPhy::StartTx. The channel attempts to deliver the PPDU to all other YansWifiPhy objects on the channel (except for the sender).
