2. DSDV
3. DSR
4. OLSR

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/flow-monitor-helper.h"

four files got generated
AODV.csv
AODV.mob
AODV.flomon
temp.data

Parameters:
Number of nodes: 50
No of sinks : 10
Mobility Model:
Propagation Model: ConstantSpeedPropagationDelay
Propagation Loss Model: Friis
Position Allocator: RandomRectangularPositionAllocator
Mac: AdhocWifiMAC
Mac Standard: 802.11B
Bps: 2Kbps
Total Simulation Time: 200 seconds
Node speed: 20m/s
Node pause time: 0
Protocol: AODV


To run the flowmon file, use of temp.py is advised.

to run the file, use the following

$] python flow.py AODV.flowmon

Find the python script here.

#beginning of Script

from xml.etree import ElementTree as ET
import sys
import matplotlib.pyplot as pylab
et=ET.parse(sys.argv[1])
bitrates=[]
losses=[]
delays=[]
for flow in et.findall("FlowStats/Flow"):
for tpl in et.findall("Ipv4FlowClassifier/Flow"):
if tpl.get('flowId')==flow.get('flowId'):
break
if tpl.get('destinationPort')=='654':
continue
losses.append(int(flow.get('lostPackets')))

rxPackets=int(flow.get('rxPackets'))
if rxPackets==0:
bitrates.append(0)
else:
t0=float(flow.get('timeFirstRxPacket')[:-2])
t1=float(flow.get("timeLastRxPacket")[:-2])
duration=(t1-t0)*1e-9
bitrates.append(8*long(flow.get("rxBytes"))/duration*1e-3)
delays.append(float(flow.get('delaySum')[:-2])*1e-9/rxPackets)

pylab.subplot(311)
pylab.hist(bitrates,bins=40)
pylab.xlabel("Flow Bit Rates (b/s)")
pylab.ylabel("Number of Flows")

pylab.subplot(312)
pylab.hist(bitrates,bins=40)
pylab.xlabel("No of Lost Packets")
pylab.ylabel("Number of Flows")

pylab.subplot(313)
pylab.hist(bitrates,bins=10)
pylab.xlabel("Delay in Seconds")
pylab.ylabel("Number of Flows")

pylab.subplots_adjust(hspace=0.4)
pylab.savefig("results.pdf")

#End of Script

We can plot using gnuplot (through CSV File) and matplotlib(Flow monitor)
All these examples, runs for 50 nodes

whenever you compare protocols,have three different sets of node numbers

10 nodes, 50 nodes, 100 nodes and compare them with various metrics as mentioned above...

To analsyse .tr files, we need to use tracemetrics
its a jar file that can be run using

$] java -jar tracemetrics.jar

Hope you would have got an idea on how to simulate wireless protocols using ns3.

  1. Dear Sir, how i can simulate VANET routing protocol in NS3.29 using SUMO 1.2.0 and MOVE.jar on windows 10

  2. you're the king, man! such explicit and down-to-earth c++ codes and other files explanation, I've never seen a better one elsewhere! thx for your effort!

  3. Hello, i can use on this script ENERGY MODEL, how i can use? can you help me? i need compare AODV,OLSR and DSDV energy consumption.
    thank you for your help!

  4. Many Thanks for the nice video and explanation. Can i modify the code to use TCP instead of UDP? How ?

    Regards

  5. Hello, thank you for the videos and the explanation I tried to do the same steps with OLSR but the result file has no output.. "I did change the destination port as in OLSR.flowmon and there is no error, yet there is no output.

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…
