Member Function Documentation

◆ AssignStreams()

int64_t ns3::PropagationLossModel::AssignStreams ( int64_t stream )

If this loss model uses objects of type RandomVariableStream, set the stream numbers to the integers starting with the offset 'stream'.

Return the number of streams (possibly zero) that have been assigned. If there are PropagationLossModels chained together, this method will also assign streams to the downstream models.

Parameters

stream the stream index offset start

Returns: the number of stream indices assigned by this model

◆ CalcRxPower()

double ns3::PropagationLossModel::CalcRxPower	(	double	txPowerDbm,
		Ptr< MobilityModel >	a,
		Ptr< MobilityModel >	b ) const

Returns the Rx Power taking into account all the PropagationLossModel(s) chained to the current one.

Parameters

txPowerDbm	current transmission power (in dBm)
a	the mobility model of the source
b	the mobility model of the destination

Returns: the reception power after adding/multiplying propagation loss (in dBm)

◆ DoAssignStreams()

virtual int64_t ns3::PropagationLossModel::DoAssignStreams ( int64_t stream )

protectedpure virtual

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

Subclasses must implement this; those not using random variables can return zero.

Parameters

stream first stream index to use

Returns: the number of stream indices assigned by this model

◆ DoCalcRxPower()

virtual double ns3::PropagationLossModel::DoCalcRxPower	(	double	txPowerDbm,

PropagationLossModel.

Parameters

txPowerDbm	current transmission power (in dBm)
a	the mobility model of the source
b	the mobility model of the destination

Returns: the reception power after adding/multiplying propagation loss (in dBm)

◆ GetNext()

Ptr< PropagationLossModel > ns3::PropagationLossModel::GetNext ( )

Gets the next PropagationLossModel in the chain of loss models that act on the signal.

Returns: The next PropagationLossModel in the chain

This method of chaining propagation loss models only works commutatively if the propagation loss of all models in the chain are independent of transmit power.

◆ GetTypeId()

◆ SetNext()

void ns3::PropagationLossModel::SetNext ( Ptr< PropagationLossModel > next )

Enables a chain of loss models to act on the signal.

Parameters

next	The next PropagationLossModel to add to the chain

This method of chaining propagation loss models only works commutatively if the propagation loss of all models in the chain are independent of transmit power.
