Installing ns-3.37 and ns-3.35 in Ubuntu | Ubuntu 22.04 | NS3

Multiple Versions of ns3 in Ubuntu 22.04 In this post, we are going to install two versions of ns3 namely ns-3.35 and ns-3.37  My OS is : Ubuntu 22.04 LTS (Long Term Support) ns-3.35 uses waf and (./waf --run scratch/first)  ns-3.37 uses cmake  (./ns3 run scratch/first.cc) So we will install both the packages  Go through the video for complete instructions To start with  $ sudo apt update  $ sudo apt install build-essential autoconf automake libxmu-dev g++ python3 python3-dev pkg-config sqlite3 cmake python3-setuptools git qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools gir1.2-goocanvas-2.0 python3-gi python3-gi-cairo python3-pygraphviz gir1.2-gtk-3.0 ipython3 openmpi-bin openmpi-common openmpi-doc libopenmpi-dev autoconf cvs bzr unrar gsl-bin libgsl-dev libgslcblas0 wireshark tcpdump sqlite sqlite3 libsqlite3-dev  libxml2 libxml2-dev libc6-dev libc6-dev-i386 libclang-dev llvm-dev automake python3-pip libxml2 libxml2-dev libboost-all-dev  I have downloaded both the versions of ns3 fr

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_;

tora.h
Tora.h Change

Change 2: tora.cc
Open the tora.cc and include the following lines in the "int toraAgent::command(int argc, const char*const* argv) " function as indicated in the figure below.
else if (strcmp(argv[1], "port-dmux") == 0) {
       dmux_ = (PortClassifier *)TclObject::lookup(argv[2]);
       if (dmux_ == 0) {
         fprintf (stderr, "%s: %s lookup of %s failed\n", __FILE__, argv[1], argv[2]);
       return TCL_ERROR;
            }
            return TCL_OK;
            }
tora
Tora.cc Change

Change 3: imep.cc
In the file imep.cc, change the following line 


rexmitTimer.start(rexat - CURRENT_TIME);

to 
if (rexat-CURRENT_TIME<0.000001) // Preventing eternal loop.
rexmitTimer.start(0.000001);
else
rexmitTimer.start(rexat - CURRENT_TIME);

imep
IMEP Change

Step 3: 
We need to recompile ns2 using the command make from the folder ns-2.35/

Once the changes are made, Open the Terminal and go to ~ns-2.35 and execute the command  

prompt$] make 

Step 4: Run the tcl file now

$] ns TORA.tcl
This file is generated in Step 1

I will give all these files to you for your simulation.

Copy the tora.cc and tora.h file in your ns-2.35/tora folder

then copy the imep.cc file in to the ns-2.35/imep folder 

and then copy the TORA.tcl file in your home folder or any folder.

Then do the compilation $] make 
and then run the TORA.tcl file using $] ns TORA.tcl
