Detailed Description

SpectrumChannel implementation which handles a single spectrum model.

All SpectrumPhy layers attached to this SpectrumChannel

Config Paths

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

/ChannelList/[i]/$ns3::SingleModelSpectrumChannel
/ChannelList/[i]/$ns3::SpectrumChannel/$ns3::SingleModelSpectrumChannel

Attributes

MaxLossDb: If a single-frequency PropagationLossModel is used, this value represents the maximum loss in dB for which transmissions will be passed to the receiving PHY. Signals for which the PropagationLossModel returns a loss bigger than this value will not be propagated to the receiver. This parameter is to be used to reduce the computational load by not propagating signals that are far beyond the interference range. Note that the default value corresponds to considering all signals for reception. Tune this value with care.
- Set with class: ns3::DoubleValue
- Underlying type: double -1.79769e+308:1.79769e+308
- Initial value: 1e+09
- Flags: construct write read

Attributes defined in parent class ns3::Channel

Id: The id (unique integer) of this Channel.
- Set with class: ns3::UintegerValue
- Underlying type: uint32_t 0:4294967295
- Flags: read

TraceSources

PathLoss: This trace is fired whenever a new path loss value is calculated. The first and second parameters to the trace are pointers respectively to the TX and RX SpectrumPhy instances, whereas the third parameters is the loss value in dB. Note that the loss value reported by this trace is the single-frequency loss value obtained by evaluating only the TX and RX AntennaModels and the PropagationLossModel. In particular, note that SpectrumPropagationLossModel (even if present) is never used to evaluate the loss value reported in this trace.

Member Function Documentation

void ns3::SingleModelSpectrumChannel::AddPropagationLossModel ( Ptr< PropagationLossModel > loss )

virtual

set the single-frequency propagation loss model to be used

Warning: only models that do not depend on the TX power should be used.

Parameters

loss	a pointer to the propagation loss model to be used.

Implements ns3::SpectrumChannel.

Definition at line 234 of file single-model-spectrum-channel.cc.

References m_propagationLoss, NS_ASSERT, and NS_LOG_FUNCTION.

void ns3::SingleModelSpectrumChannel::AddRx ( Ptr< SpectrumPhy > phy )

virtual

add a SpectrumPhy to a channel, so it can receive packets

This method is used to attach a SpectrumPhy instance to a SpectrumChannel instance, so that the SpectrumPhy can receive packets sent on that channel. Note that a SpectrumPhy that only transmits (without receiveing ever) does not need to be added to the channel.

This method is to be implemented by all classes inheriting from SpectrumChannel.

Parameters

phy	the SpectrumPhy instance to be added to the channel as a receiver.

Implements ns3::SpectrumChannel.

Definition at line 101 of file single-model-spectrum-channel.cc.

References m_phyList, and NS_LOG_FUNCTION.

void ns3::SingleModelSpectrumChannel::AddSpectrumPropagationLossModel ( Ptr< SpectrumPropagationLossModel > loss )

virtual

set the frequency-dependent propagation loss model to be used

Parameters

loss	a pointer to the propagation loss model to be used.

Implements ns3::SpectrumChannel.

Definition at line 243 of file single-model-spectrum-channel.cc.

References m_spectrumPropagationLoss, NS_ASSERT, and NS_LOG_FUNCTION.

void ns3::SingleModelSpectrumChannel::DoDispose ( void )

privatevirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

Definition at line 55 of file single-model-spectrum-channel.cc.
