Graphics.h in Linux Mint or Ubuntu

This post tells you how to install graphics.h in either Ubuntu or Linux Mint

Parameters:
OS : Linux Mint 17.1 - 64 bit OS

Usually graphics.h will not be available in Linux Mint and if you want to include that in Ubuntu or Mint, here are the steps and a sample program

$ sudo apt-get update
$ sudo apt-get install build-essential autoconf automake libxmu-dev 
The above line is needed to get all the developmental libraries for ubuntu or mint. 

$ sudo apt-get install libsdl-image1.2 libsdl-image1.2-dev guile-1.8 guile-1.8-dev libsdl1.2debian libart-2.0-dev libaudiofile-dev libesd0-dev libdirectfb-dev libdirectfb-extra libfreetype6-dev libxext-dev x11proto-xext-dev libfreetype6 libaa1 libaa1-dev libslang2-dev libasound2 libasound2-dev

The above line is needed to download the complete graphics with sound libraries

Download this file libgraph
http://download.savannah.gnu.org/releases/libgraph/libgraph-1.0.2.tar.gz

Go the download location and unzip it
$ tar zxvf libgraph-1.0.2.tar.gz
$ cd libgraph-1.0.2/
$ ./configure
$ sudo make
$ sudo make install
$ sudo cp /usr/local/lib/libgraph.* /usr/lib

Once done, its ready to run the graphics.h file

Here are two examples, one to plot  stars in space

/*A program to draw a space with stars*/
#include <graphics.h>
int main()
{
  int gd=DETECT,gm;
  int i,x,y;
  initgraph(&gd,&gm,NULL);
  line(0,0,640,0);
  line(0,0,0,480);
  line(639,0,639,480);
  line(639,479,0,479);
  for(i=0;i<=1000;i++)
  {
    x=rand()%639;
    y=rand()%480;
    putpixel(x,y,15);
  }
getch();
  closegraph();
}
/* End of program */
Here is the output
graphics.h
Graphics Program for Stars



Program 2: A Program to plot a Bar Graph (Histogram)
/*Here a sample program to illustrate how to use BARS which are used for visual statistics */
#include <graphics.h>
int main() {
  int gd=DETECT,gm,maxx,maxy,x,y,button;
  initgraph(&gd,&gm,"");
  line(80,150,200,150);
  line(80,150,80,50);  

outtextxy(100,153,"<-X axis");
  outtextxy(60,50,"<-Y axis");
  bar(100,100,120,150);
  bar(130,120,150,150);
  getch();
  closegraph();
}

Here is the output
graphics.h
Graphics.h for Bar Chart

Installation of ns2 in Ubuntu 18.04 - NS2 Tutorial # 2

ns2 installation in Ubuntu 18.04

Unlike earlier version of ubuntu, the 18,04 version does not support the direct installation of ns2, because of the latest C/C++ compiler (7.x), but the latest C/C++ compiler supported by ns2 is gcc-4.8. So this post and video tells you about the installation of gcc-4.8 version, then ns2 and then configuration.
Here are the steps, Please follow the video given below for more information.

$] tar zxvf ns-allinone-2.35.tar.gz


$] sudo apt install gcc-4.8 g++-4.8

if you have installed ubuntu just now, you can try these commands also in the beginning

$] sudo apt update
$] sudo apt install build-essential autoconf automake libxmu-dev

$] cd ns-allinone-2.35/ns-2.35
$] gedit Makefile.in
$] gedit linkstate/ls.h

line number 137, change erase to this->erase
$] cd ..
$] ./install

export PATH=$PATH:/home/pradeepkumar/ns-allinone-2.35/bin:/home/pradeepkumar/ns-allinone-2.35/tcl8.5.10/unix:/home/pradeepkumar/ns-allinone-2.35/tk8.5.10/unix

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.

AWK Scripts for NS2 to process data from Trace Files

AWK Scripts are very good in processing the data from the log (trace files) which we get from NS2. If you want to process the trace file manually, here is the detailHere is a sample of trace file from NS2 (However ns2 supports a new type of trace file also), but this post will make you understand the old trace format only.r 0.030085562 _0_ MAC  --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] r 0.030110562 _0_ RTR  --- 0 message 32 [0 ffffffff 1 800] ------- [1:255 -1:255 32 0] s 1.119926192 _0_ RTR  --- 1 message 32 [0 0 0 0] ------- [0:255 -1:255 32 0]
AWK Scripts are very good in processing the data column wise. For example
the first column in the above trace file represents r, s which indicates receive, sent respectively. If we want to trace the entire r and s alone from this trace file we can represent it as $1
So
$1 represents ACTION
$2 Time
$3 Node ID
$4 Layer
$5 Flags
$6 seqno
$7 type
$8 Size
$14 Energy (if the network nodes includes EnergyModel)To run the awk script in Li…
