NS3 (Compile and Run Network Simulator Program)
1.Development Tools
NS3 support development programming C++ and Python
2.Getting Started
Code I copy paste from NS3 sample codes, main-simple.cc
#include <iostream>
#include "ns3/core-module.h"
#include "ns3/helper-module.h"
#include "ns3/node-module.h"
#include "ns3/simulator-module.h"
using namespace ns3;
static void
GenerateTraffic (Ptr<Socket> socket, uint32_t size)
{
std::cout << "at=" << Simulator::Now ().GetSeconds () << "s, tx bytes=" << size << std::endl;
socket->Send (Create<Packet> (size));
if (size > 0)
{
Simulator::Schedule (Seconds (0.5), &GenerateTraffic, socket, size - 50);
}
else
{
socket->Close ();
}
}
static void
SocketPrinter (Ptr<Socket> socket)
{
Ptr<Packet> packet;
while (packet = socket->Recv ())
{
std::cout << "at=" << Simulator::Now ().GetSeconds () << "s, rx bytes=" << packet->GetSize () << std::endl;
}
}
static void
PrintTraffic (Ptr<Socket> socket)
{
socket->SetRecvCallback (MakeCallback (&SocketPrinter));
}
void
RunSimulation (void)
{
NodeContainer c;
c.Create (1);
InternetStackHelper internet;
internet.Install (c);
TypeId tid = TypeId::LookupByName ("ns3::UdpSocketFactory");
Ptr<Socket> sink = Socket::CreateSocket (c.Get (0), tid);
InetSocketAddress local = InetSocketAddress (Ipv4Address::GetAny (), 80);
sink->Bind (local);
Ptr<Socket> source = Socket::CreateSocket (c.Get (0), tid);
InetSocketAddress remote = InetSocketAddress (Ipv4Address::GetLoopback (), 80);
source->Connect (remote);
GenerateTraffic (source, 500);
PrintTraffic (sink);
Simulator::Run ();
Simulator::Destroy ();
}
int main (int argc, char *argv[])
{
RunSimulation ();
return 0;
}

def build(bld):
env = bld.env_of_name('default')
if not env['ENABLE_EXAMPLES']:
return;
obj = bld.create_ns3_program('hello-world-ns3',
['core', 'simulator'])
obj.source = 'hello-world-ns3.cc'
3.Create waf file and write this script exec "`dirname "$0"`"/../waf "$@"
4.Compile and Run
./waf --run "hello-world-ns3"
Prerequisites
The following list of packages should be accurate for Ubuntu 10.10 release.
requirements for C++ (release)
sudo apt-get install gcc g++ python
requirements for Python (release)
sudo apt-get install gcc g++ python python-dev
Mercurial:
sudo apt-get install mercurial
python bindings:
sudo apt-get install bzr
Debugging
sudo apt-get install gdb valgrind
GNU Scientific Library (GSL):
sudo apt-get install gsl-bin libgsl0-dev libgsl0ldbl
The Network Simulation Cradle (nsc):
sudo apt-get install flex bison
To read pcap packet traces:
sudo apt-get install tcpdump
Sqlite for statistics framework
sudo apt-get install sqlite sqlite3 libsqlite3-dev
Xml-based version of the config store
sudo apt-get install libxml2 libxml2-dev
A GTK-based
sudo apt-get install libgtk2.0-0 libgtk2.0-dev
To experiment with virtual machines and ns-3
sudo apt-get install vtun lxc
utils/check-style.py code style check program
sudo apt-get install uncrustify
Doxygen
sudo apt-get install doxygen graphviz imagemagick
sudo apt-get install texlive texlive-latex-extra texlive-generic-extra texlive-generic recommended
Texinfo
sudo apt-get install texinfo dia texlive texlive-latex-extra texlive-extra-utils texlive-generic-recommended texi2html
ustavo Carneiro's ns-3-pyviz visualizer
sudo apt-get install python-pygraphviz python-kiwi python-pygoocanvas libgoocanvas-dev
Installation
Now we can start to install NS3. Firstly we download ns-allinone-3.9.tar.bz2 file and put on a specific folder such as repos
Extract ns-allinone-3.9.tar.bz2
tar xjf ns-allinone-3.9.tar.bz2
Change to directory ns-allinone-3.9 and build NS3
./build.py
If success, you can see output messages displayed as below
'build' finished successfully (..)
Leaving directory './ns-3.9'
