What Version: ns-3.29
My Ubunut OS is: Ubuntu 18.04

This file we are going to use for our simulation:
/home/networks/ns-allinone-3.29/ns-3.29/examples/routing/manet-routing-compare.cc

Once you under stand the code, now lets run this example

Step 1: Copy the above file in to ~ns-3.29/scratch/ folder

Step 2: Understand this code.
Step 3: Run this code
Open the terminal, Go to ns-3.29 and run the following command

$] ./waf --run scratch/manet-routing-compare

enable the following header file

#include "ns3/flo…

SUMO, Open Street Maps and NS2 - A Real Traffic Simulation

SUMO is the Simulation of Urban mobility software that enables to simulate the road traffic. Open Street map (www.openstreetmap.org)  provides the xml based .osm file for any part of the world selected through their website. #openstreetmap

#SUMO can able to convert the osm file to its native xml file. The post tells you the simulation of a real traffic network and how it is ported to #ns2 for network animation and tracing.

Step 1: Prerequisites

  • SUMO to be installed - in my case I installed sumo this way 
sudo add-apt-repository pap:sumo/stable
sudo apt-get update
sudo apt-get install sumo sumo-doc sumo-tools

Also, Download the sumo source sumo-src-0.26.tar.gz from this link and unzip or untar it to the home directory (/home/pradeepkumar). There are some python files that are needed to generate random trips and to export xml files to tcl files. the commands sumo, sumo-gui will run only the graphical simulation.
Once the software is unzipped, set the SUMO_HOME in the environment, Open /home/pradeepkumar/.profile (for Linux Mint) and /home/pradeepkumar/.bashrc (for Ubuntu) and give this command (in my case the home is pradeepkumar, it might be different for you)
export SUMO_HOME=/home/pradeepkumar/sumo-0.26.0 

Step 2: Steps to create a Traffic

  1. Open browser and type http://www.openstreetmap.org and search a particular area and click export in the top. 
  2. click "Manually select an area" and select the area (as shown in the video below) and click export again (it will download a file called map.osm, rename this file as per your convenience)
  3. Open the terminal and type the commands one by one (assume my file name is guindy.osm, so i maintain the same file name guindy for all the xml files)
$] netconvert --osm-files guindy.osm -o guindy.net.xml

Now, copy the osmPolyconvert.typ.xml from the $SUMO_HOME/data/typemap/ and copy it to the folder where you put all the files. 


$] polyconvert --osm-files guindy.osm --net-file guindy.net.xml --type-file osmPolyconvert.typ.xml -o guindy.poly.xml



$] python $SUMO_HOME/tools/randomTrips.py -n guindy.net.xml -r guindy.rou.xml -e 100 -l

Now, create a new file (to be named as guindy.sumo.cfg) and paste the following lines 

 <configuration>
     <input>
         <net-file value="guindy.net.xml"/>
<route-files value="guindy.rou.xml"/>
         <additional-files value="guindy.poly.xml"/>
     </input>
<time>
<begin value="0"/>
<end value="100"/>
<step-length value="0.1"/>
</time>
 </configuration>

Now you can run the above using sumo-gui guindy.sumo.cfg (now you can see as per the following screenshot)
sumo
SUMO


Step 3: Exporting to NS2
from sumo trace to ns2, here is the step to do
Open terminal and type the following commands,

$] sumo -c guindy.sumo.cfg --fcd-output guindy.sumo.xml


$] python /home/pradeepkumar/sumo-0.26.0/tools/traceExporter.py --fcd-input guindy.sumo.xml --ns2config-output guindy.tcl --ns2activity-output activity.tcl --ns2mobility-output mobility.tcl​

This will generate three tcl files (guindy.tcl, activity.tcl and mobility.tcl). Among this activity.tcl might not be needed, but mobility.tcl file is mandatory)

The generated guindy.tcl have to be modified or altered as per the networking parameters like routing protocol, Mac layer, physical layer, link layer, etc.

You can see the following video for all the instructions.




A Sample TCL File for your Use

Here is the guindy.tcl file, you can use it for your purpose

This post serves the installation instructions of ns3 in ubuntu 16.04 version. Some of my students are working in ns3, this post will benefit them in installing ns3.

OS Used: Ubuntu 16.04.4
ns3 version: ns3 version 3.27

The same procedure will be applied for OS like Debian, Linux Mint.

Fresh installation of Ubuntu 16.04 Let you try the fresh installation of ubuntu in your hard disk along with windows.
Installation of ns3 dependencies ns3 needs so many dependencies, developmental libraries, drivers, etc. so install all those

TORA Protocol in NS-2.35 (NS2)

This post tells you how to enable the TORA (Temporally ordered routing Algorithm) protocol in Network Simulator 2 (ns-2.35)

TORA is a protocol in wireless adhoc networks that works with timing parameters. NS-2.35 comes with the TORA protocol by default but it has to be tweaked manually to make it run.
This post will help you to do that.

You can watch this video for detailed instructions:


Step 1: Generate a Scenario for TORA protoco using NS2 Scenario Generator NSG Software.
We have created a tcl file using NSG2.1.jar

$] java -jar NSG2.1.jar

Three files have to be modified
~ns-2.35/tora/tora.cc~ns-2.35/tora/tora.h~ns-2.35/imep/imep.cc There are various websites that tells you how to configure TORA by making changes to the above three files.  Change 1: tora.h In the tora.h file, go to the end of the File before the agent completes, include these two lines

#include <classifier/classifier-port.h>
protected: PortClassifier *dmux_;

Change 2: tora.cc Open the tora.cc and include the follow…
