Network Simulator 3 (NS-3)

Introduction

One of the tools that I will be using for my research is NS-3 (Network Simulator Version 3). NS-3 is a discrete-event network simulator written in C++ with Python bindings, targeted primarily for research and educational use. Discrete event simulation models the behaviour of a complex system as an ordered sequence of well-defined events. Time moves discretely from event to event. This contrasts with continuous simulation in which the simulation continuously tracks the system dynamics over time.

Download NS-3 (current version is 3.26 as of this writing)


wget http://www.nsnam.org/release/ns-allinone-3.26.tar.bz2
tar xfj ns-allinone-3.26.tar.bz2
cd ns-allinone-3.26 

Build, configure and test


./build.py --enable-examples --enable-tests
cd ns-3.26
./waf -d debug --enable-examples --enable-tests configure
./waf
./test.py

Configure Eclipse for NS-3 Coding

  1. Download Eclipse for C++ developers from here. You also need Java.
  2. Start eclipse and configure mercurial. You do this by going to Help -> Eclipse Marketplace… and search for “MercurialEclipse Project”
  3. Create a new C++ project (let’s call its it ns326) in the ns-3 root folder. Select Cross GCC as the ToolChain {This is important}. Click Next, leave “Debug” and “Release” selected for now and click Next and Finish
  4. Right click on your project (ns326 in my case), select Team -> Share Project…. Select Mercurial then Next and Finish
  5. The next thing to do is to configure WAF. Right click on the project (ns326 in my case) and choose properties. Select C/C++ Build and uncheck “Use default build command” and “Generate Makefiles automatically”. Replace “Build command” with {your-project-path/waf}. In my case that would be /home/tony/ns-allinone-3.26/ns-3.26/waf and configure Build directory as {your-project-path/build}, /home/tony/ns-allinone-3.26/ns-3.26/build in my case. Select Behavior tab and uncheck everything. Select Build (incremental build) again and type build then select Clean and Stop on first build error and click OK
  6. The last thing is to configure the debugger. Click Run -> Debug Configurations -> Under Project: click on browse and select your project (ns326 in my case), under C/C++ Application type and select scratch-simulator. [Remove any spaces under project Name. Select Environment tab and click New.. variable and add LD_LIBRARY_PATH under name and {Your project path}/build, /home/tony/ns-allinone-3.26/ns-3.26/build in my case. Apply and close.
