Gnuplot to plot histograms
To plot histograms using Gnuplot, please follow the steps given below. Gnuplot supports various techniques on historgrams like

  • Clustered
  • RowStacked
  • ColumnStacked
  • etc.
Use the following video to watch the complete steps and description

Steps for Gnuplot

Part 1 - Gnuplot (Already In my youtube Channel)
Part 2 - Histogram

Step 1: Create a Data File
Air Quality Index for famous cities across the world.

#Filename is:
Chennai 323 278 567
Turkey 890 765 456
Andorra 7 7 98
Palestine 70 67 56
Bulgaria 159 123 100
China 677 478 123
Netherlands 52 76 43

Step 2 : Write the GNU COde.

#filename: gnucode.txt
set terminal pdf
set output "aqi.pdf"
set title "Air Quality Index"
set style data histogram
set style fill solid
set style histogram clustered
plot for [COL=2:4] "" using COL:xtic(1) title "AQI"

The following is the output in the pdf file that is generated within the same folder
Gnuplot histograms

Store both the above files in one folder

To run the above file,

Open the Terminal
$] gnuplot gnucode.txt

Data and Code in the Same File
In case if the plotting data and the source code for gnuplot is in the same file, then here is the steps

set terminal pdf
set output "aqi2.pdf"
set title "Air Quality Index"
set style data histogram
set style fill solid
set xtic rotate out
#set style histogram clustered
plot "-" using 2:xtic(1) title "AQI"
Delhi 100
Chennai 98
Mumbai 87
Pune 67
Madurai 17

This the following output

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/ 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: Open the and include the follow…
