[ndnSIM] Help Needed: Getting Node Name in Forwarder.cpp for Output Logging

[DJEMAA Adel]

Dear Mohammad,
Try this code to retrieve node names in Forwader.cpp file:
auto  node = ns3::NodeList::GetNode(ns3::Simulator::GetContext());
std::cout<<" ************ Node ID :****************"<< node->GetId()
<<std::endl;
You need to include these:
#include <ns3/node-list.h>
#include <ns3/node.h>
Let us know if this answers your question.
kind regards;
