Detailed Description

This class implements the error model described in this paper: N.

Baldo and M. Miozzo, "Spectrum-aware Channel and PHY layer modeling for ns3", in Proceedings of International Workshop on Network Simulation Tools (NSTOOLS 2009), 19 October 2009, Pisa (Italy).

Member Function Documentation

◆ DoDispose()

void ns3::ShannonSpectrumErrorModel::DoDispose ( )
overrideprotectedvirtual

Destructor implementation.

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

Subclasses are expected to implement their real destruction code in an overridden 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.
