Security Protocol (packet) in NS2

Security is not my area of work, but most of the places, I have been bombarded with questions like , is it possible to implement security protocol in ns2.
The answer is yes, here is the solution for that.  Here is the document to read
This work is done in 2005 and developed for ns version 2.26 or 2.27. I have done the compilation for ns-2.35
The files to be modified
1. Create a new agent called "Security_packet" and two files Security_packet.h and Security_packet.cc are created.
2. Add a new packet type in ~ns-2.35/common/packet.h
3. Add a new packet type in ~ns-2.35/tcl/lib/ns-default.tcl
4. Add a new packet type in ~ns-2.35/tcl/lib/ns-packet.tcl
5. modify the ~ns-2.35/Makefile.in

Steps
1. Download the two files here
2. Copy the security.cc and security.h file in ~ns-2.35/security folder (create the security/ folder and paste both the files)
3. Open ~ns-2.35/Makefile.in and make an entry as shown below,
OBJ_CC =
......
...
             security/security.o

security
Makefile
4. Open the ~ns-2.35/common/packet.h file
There will be two changes
Change one
static const packet_t PT_SECURITY_PACKET=74;
as shown below
security
packet.h
and another change
name_[PT_SECURITY_PACKET]= "Security_packet";
as shown below

security
packet.h


5. Open the file ~ns-2.35/tcl/lib/ns-default.tcl, and paste the following line at the end of the file
Agent/Security_packet set packetSize_ 0

See below
security
ns-default.tcl
6.  open the file ~ns-2.35/tcl/lib/ns-packet.tcl, Input the following line 
Security_packet
as shown below
Security
ns-packet.tcl

To Compile

Open the terminal, 
$] cd ~ns-allinone-2.35/ns-2.35/
$] ./configure
$] make

Run the security.tcl file using the ns command 
$] ns security.tcl

See the output, Since my area is not on the security, read the document/source code yourself
Security
Security

Thats it!!!

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…
