Ant Colony Algorithm (antnet) in NS-2.35

The source code of antnet is taken from this website. If anyone claims as the owner of this software, let me know so that I will give credits to him/her.

(NB: This topic does not have any relevance to me and I have just reproduced what was available in the above website). And of Course, corrected some bugs. 

Important: These codes will work well with fresh installation of ns-allinone-2.35. If you have already compiled any other simulation in ns-2.35, kindly take a back up before you proceed.

These are the files to be modified. Download the entire folder here
...ns-2.35/tcl/lib/ns-default.tcl 
...ns-2.35/common/packet.h    
rtable.txt (This file is created for my network with 2 nodes)
...ns-2.35/trace/cmu-trace.cc 
...ns-2.35/queue/drop-tail.h
...ns-2.35/tcl/lib/ns-lib.tcl      
...ns-2.35/queue/priqueue.cc  
simpleant.tcl (This is the tcl file can be copied anywhere)
...ns-2.35/trace/cmu-trace.h  
...ns-2.35/Makefile.in
...ns-2.35/tcl/lib/ns-packet.tcl   
...ns-2.35/queue/priqueue.h   
antnet_281_29.tar.gz (this will be original algorithm) 
...ns-2.35/queue/drop-tail.cc

Step 1: Download all the files

Step 2: Copy each file to the original location as given above (One main problem when you copy paste from the web is, some symbols like -, ", ->,_, are formatted automatically for web standards, but C programming or any programming language accepts only ASCII Codes. So whenever you copy paste codes in C programming, ensure that all symbols are of ASCII.  Else the compiler may throw as \364, etc stray program error.
(So all the codes that you download from my link are ASCII complaint codes, Yes I have modified, You can compile the codes with minimal effort)

Step 3: Unzip the antnet_281_29.tar.gz and paste the antnet/ folder to ..ns-2.35/
(This will be main algorithm, Open the code and understand)

Step 4: Open the Terminal and go to ns-2.35  (in my case it is /home/pradeepkumar/ns-allinone-2.35/ns-2.35/)
$]  cd /home/pradeepkumar/ns-allinone-2.35/ns-2.35/
$] ./configure 
$] make clean  (This command may be used if you have any problem in creating the .o files)
$] make 

Step 5: Run the simpleant.tcl using
$] ns simpleant.tcl 
This will create three files,
rtable.txt (The routing table of all the nodes)
simple.nam ( A network animation file)
simple.out (A Trace file)

Here is the sample output
antnet

contents of rtable.txt

  3. Hi Pradeep i am facing problem when i use "make" command.
    the problem is on terminal i get "undefined reference to 'hdr_ant_pkt::offset_'".
    Kindly need your feedback that why i am facing this failure?

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…
