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

Comparison of AODV, DSR and DSDV in ns2 - NS2 Tutorial # 9

Performance Evaluation of Adhoc Routing Protocols using NS2

Very old Project as well as a topic, but this will give an idea of how to compare multiple protocols or agents.

1 hour Project*

See the video for the full project


* - you should know ns2 already
should know how to write AWK scripts
Should know about energy model
Should know about wireless networks and protocols

To know the above concepts, check my Ns2 Lecture series videos in Youtube and come back to this video

Youtube.com/tspradeepkumar

AODV, DSDV and DSR
AODV - Adhoc On Demand Distance Vector
DSDV - Destination Sequenced Distance Vector
DSR - Dynamic Source Routing

Lcture 8 - AWK Scripts
Average throughput
Instant throughput
Residual Energy
Packet Delivery ratio

To download the source codes, visit https://www.nsnam.com

Going inside the project

Step 1:
Use the same network and same disntace, energy, etc when you compare multiple protocols

Step 2:
Generate Scenario, You need not write the code in TCL (of course you can modify).
We use NSG for creating a network. Refer my lecture series on NSG (NS2 scenario Generator)

$] java -jar NSG2.1.jar

As seen in the GUI, Create a network (for example with 17 nodes) and two nodes are moving
with a interference of 550 metres and tranmission range of 250metres.

Create a network with a AODV protocol

Create two copies of AODV protocol and name it as DSR.tcl and DSDV.tcl

$] cp AODV.tcl DSR.tcl
$] cp AODV.tcl DSDV.tcl


Three files are ready now called
AODV.tcl, DSR.tcl, DSDV.tcl

and now these three files using ns filename.tcl

$] ns AODV.tcl
$] ns DSR.tcl
$] ns DSDV.tcl
I have the three files and got 9 files namely
AODV.tr, DSDV.tr and DSR.tr
AODV.nam, DSDV.nam and DSR.nam

There is no energy coding, i need to implement that

DSR does not obey the queue model as specified for AODV,
Queue/DropTail/PriQueue  is not supported by DSR, we have to go for CMUPriQueue

DSR supports this queue called CMUPriQueue, it should reflect in the tcl code.

All the tcl files run successfully. now we are going to analyse the results and sometime plot the graphs too.

we have already written AWK scripts for Average throughput, instant throughput , residual energy and packet delivery ratio

average_throu.awk
instant_throu.awk
pdr.awk
resenergy.awk

To run these scripts we need awk interpreter as below

$] gawk -f resenergy.awk AODV.tr
$] gawk -f resenergy.awk DSDV.tr
$] gawk -f resenergy.awk DSR.tr

Whenvern you compare multiple protocols
Use three different sets of nodes

Small number of nodes (10 nos)
Medium number of nodes (20 to 30 nos)
Huge number of nodes (upto 100)

beyond 100 nodes, ns2 suffers.

in this case, we did it for 17 nodes only. You can do the rest.
So we are coming to the conclusion

Comparing protocols needs
1. Three minimum protocols (AODV, DSR, DSDV)
TCP, TCPReno, TCPVegas, FullTCP
2. number of nodes (small, medium and huge) as mentioned above, 10 nodes, 30 nodes, 100 nodes
3. Atleast three performance metrics, in this case we have, average throghput, instant througput, residual energy and packet delivery ratio
4. Strong knowledge on the protocols
5. AWK scripts to be known or atleast to be downloaded.
6. Design the network rather than coding the network, use scenario generators for ns2.

Our project is complete!!! Stay tuned

  1. can you please clear, where you have specified total packet size sending in awk script so that you are receiving 445 as a received packet during the calculation of avg. throughout?

ns3 installation in Ubuntu 16.04

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
$] sudo apt update  $] sudo apt upgrade
$] sudo apt-get install build-essential autoconf automake libxmu-dev python-pygoocanvas python-pygraphviz cvs mercurial bzr git cmake p7zip-full python-matplotlib python-tk python-dev python-kiwi python-gnome2 python-gnome2-desktop-dev python-rsvg qt4-dev-tools qt4-qmake qt4-qmake qt4-default gnuplot-x11 wireshark
The above command make take some time to download, compile and install it, Be Patient.

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…
