Detailed Description

manage and create wifi channel objects for the yans model.

The intent of this class is to make it easy to create a channel object which implements the yans channel model. The yans channel model is described in "Yet Another Network Simulator", http://cutebugs.net/files/wns2-yans.pdf

Constructor & Destructor Documentation

◆ YansWifiChannelHelper()

ns3::YansWifiChannelHelper::YansWifiChannelHelper ( )

Create a channel helper without any parameter set.

The user must set them all to be able to call Create later.

◆ AddPropagationLoss()

void ns3::YansWifiChannelHelper::AddPropagationLoss	(	std::string	name,
		std::string	n0 = `""`,
		const AttributeValue &	v0 = `EmptyAttributeValue ()`,
		std::string	n1 = `""`,
		const AttributeValue &	v1 = `EmptyAttributeValue ()`,
		std::string	n2 = `""`,
		const AttributeValue &	v2 = `EmptyAttributeValue ()`,
		std::string	n3 = `""`,
		const AttributeValue &	v3 = `EmptyAttributeValue ()`,
		std::string	n4 = `""`,
		const AttributeValue &	v4 = `EmptyAttributeValue ()`,
		std::string	n5 = `""`,
		const AttributeValue &	v5 = `EmptyAttributeValue ()`,
		std::string	n6 = `""`,
		const AttributeValue &	v6 = `EmptyAttributeValue ()`,
		std::string	n7 = `""`,
		const AttributeValue &	v7 = `EmptyAttributeValue ()`
	)

Parameters

name	the name of the model to add
n0	the name of the attribute to set
v0	the value of the attribute to set
n1	the name of the attribute to set
v1	the value of the attribute to set
n2	the name of the attribute to set
v2	the value of the attribute to set
n3	the name of the attribute to set
v3	the value of the attribute to set
n4	the name of the attribute to set
v4	the value of the attribute to set
n5	the name of the attribute to set
v5	the value of the attribute to set
n6	the name of the attribute to set
v6	the value of the attribute to set
n7	the name of the attribute to set
v7	the value of the attribute to set

Add a propagation loss model to the set of currently-configured loss models. This method is additive to allow you to construct complex propagation loss models such as a log distance + jakes model, etc.

The order in which PropagationLossModels are added may be significant. Some propagation models are dependent of the "txPower" (eg. Nakagami model), and are therefore not commutative. The final receive power (excluding receiver gains) are calculated in the order the models are added.

◆ AssignStreams()

int64_t ns3::YansWifiChannelHelper::AssignStreams	(	Ptr< YansWifiChannel >	c,
		int64_t	stream
	)

Assign a fixed random variable stream number to the random variables used by the channel.

Typically this corresponds to random variables used in the propagation loss models. Return the number of streams (possibly zero) that have been assigned.

Parameters

c	NetDeviceContainer of the set of net devices for which the WifiNetDevice should be modified to use fixed streams
stream	first stream index to use

Returns: the number of stream indices assigned by this helper

◆ Create()

Ptr< YansWifiChannel > ns3::YansWifiChannelHelper::Create ( void ) const

Returns: a new channel

Create a channel based on the configuration parameters set previously.

◆ Default()

YansWifiChannelHelper ns3::YansWifiChannelHelper::Default ( void )

static

Create a channel helper in a default working state.

By default, we create a channel model with a propagation delay equal to a constant, the speed of light, and a propagation loss based on a log distance model with a reference loss of 46.6777 dB at reference distance of 1m.

Returns: YansWifiChannelHelper
