HOW TO RUN NS 2.34 PACKAGES IN UBUNTU

HOW TO Install NS 2.34 PACKAGES IN UBUNTU

To import ns 2.34 packages in NS2 we provide assistance. Our developers can also offer you excellent project ideas and guidance on how to implement them in your research tailored to your interest. Network Simulator 2 (NS2) is a well-known open-source tool for simulating network events. It was first created under the VINT (Virtual Inter-Network Testbed) project. NS2 helps users simulate different network protocols, routing methods, and traffic types. With this simulator, users can create custom network designs and analyze protocol performance using detailed statistics. NS2 remains an essential tool in network simulation, supporting advancements in areas like mobile networking, the Internet of Things (IoT), and protocol creation.

PRE-REQUISITES:

Fresh installation of Ubuntu 16.04 LTS:

2.System File Update Command:

First of all, we need to updates the list of available packages and their versions stored in the system’s package index. Use below command to update the system package.

Command: “sudo apt-get update”

Screenshot:

3.Install Essential Tools:

1. build-essential: A package containing essential tools for compiling software on Ubuntu, including GCC, g++, and make.
2. autoconf: A tool for automatically configuring source code packages to adapt to various UNIX-like systems.
3. automake: A tool that automatically generates Makefile.in files, simplifying the creation of portable makefiles.
4. libxmu-dev: A development package for the X11 Athena Widget library, providing miscellaneous utility functions for X Window System programs.

Command: “sudo apt-get install build-essential autoconf automake libxmu-dev”

Screenshot:

Click the key Y to install the required Essentials tools for giving permission to install the package in the user system.

Installation of the Essential tools package completed successfully.

INSTALL NETWORK SIMULATOR 2 (NS2):

Locating the ns-allinone-2.34 Folder:

Next, we need to install the NS 2 in our system so locate the Extracted ns-allinone-2.34 folder in the home directory.

Screenshot:

2.Launching the terminal in the ns-allinone-2.34 Folder:

Then Right Click in the current Directory and select the “Open in Terminal” button and it will launch the terminal.

Screenshot:

Here, we launched the terminal by that button in the folder.

3.Modification of ns2.34 Code:

Next, we need to modify the Ns-2.34 to install the network simulation 2 Environment in the User system and it will resolve some dependency errors. First of all, locate to the Ns-2.34 folder.

Command: “cd Ns-2.34”

Screenshot:

Next, we need to edit the ls.h file in the Ns-2.34 with gedit command.

Command: “cd linkstate && gedit ls.h”

Screenshot:

Next, the code this-> is added to the line 137 and before the erase (basemap::begin(), baseMap::end()) code.

Screenshot:

Next, we need to edit the ranvar.cc file in the Ns-2.34 with gedit command.

Command: “cd tools && gedit ranvar.cc”

Screenshot:

Next, In the code line 219 by removing this line “return GammaRandomVariable::GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);” and add this line “return GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);”

Screenshot:

Next, we need to edit the mac_802_11Ext.h file in the Ns-2.34 with gedit command.

Command: “cd mac && gedit mac_802_11Ext.h”

Screenshot:

Next, add “#include <stddef.h>” in line 66.

Screenshot:

Next, we need to edit the nakagami.cc file in the Ns-2.34 with gedit command.

Command: “cd mobile && gedit nakagami.cc”

Screenshot:

Next, In the code line 183 by removing this line “resultPower = ErlangRandomVariable::ErlangRandomVariable(Pr/m, int_m).value();” and add this line “resultPower = ErlangRandomVariable(Pr/m, int_m).value();”

Screenshot:

Next, In the code line 185 by removing this line “resultPower = GammaRandomVariable::GammaRandomVariable(m, Pr/m).value();” and add this line “resultPower = GammaRandomVariable(m, Pr/m).value();”

Screenshot:

4.Installing Ns-2.34 by the terminal:

Next, we need to install the network simulation 2.34 Environment in the User system and it. So, use the command to install the ns-2.34 in the ns-allinone-2.34 folder location.

Command: “./install”

Screenshot:

Ns-2.34 Configuration process:

Screenshot:

The configuration of the Network Simulator 2 (NS-2) environment. This command is typically used to set various parameters, such as the simulation duration, network topology, and node properties. It can also be used to specify the output format and other simulation settings.

Screenshot:

Ns-2.34 Configuration Completed successfully.

Ns-3.25 Building process:

Screenshot:

Next, Building the Network Simulator 2 (NS-2) framework from its source code. When use this command, It will compiles the source code, generates the Makefiles, and builds the NS-2 binary and libraries and make Runnable Environment.

Screenshot:

Ns-2.34 Installed successfully in the Ubuntu 16.04 system.
