Purpose & installation of NS2 & NAM

Purpose & installation of NS2 & NAM in Hindi | Purpose and Installation of NS2 and NAM:

 
  • Purpose and Installation of NS2 (Network Simulator 2) and NAM (Network Animator) Network simulation is an important tool for the study and development of networking and communication systems.
  • Network Simulator 2 (NS2) and Network Animator (NAM) are two major software programs that are widely used to understand the behavior of networks, data transmission, and the functioning of protocols.
  • They are used to simulate various types of network protocols (like TCP, UDP), routing algorithms, and topologies.

Here we will understand in detail the purpose and installation process of NS2 and NAM.

Purpose of NS2 in Hindi | Purpose of NS2 (Network Simulator 2)

NS2 is a discrete-event network simulation tool used to simulate the behavior of network protocols, such as data transmission, routing, and packet switching. It is widely used in research, educational institutions, and industries for the study and analysis of network protocols.

Purpose of NS2 in Hindi | Purpose of NS2:

  • Simulation of Network Protocols: The main purpose of NS2 is to simulate various network protocols, such as TCP, UDP, and other IP-based protocols. It provides a powerful tool for studying the functions of protocols in various network scenarios.
  • Analysis of Network Behavior: NS2 can be used to simulate and analyze various components of a network, such as transmission, latency, packet loss, and bandwidth utilization.
  • Development of Routing Protocols: Various routing protocols such as OSPF, AODV, DSR, etc. can be simulated in NS2. Through this simulation, network performance is measured and analyzed.
  • Wireless Networking Simulation: NS2 is capable of simulating both wired and wireless networks. It can also be used to study wireless networks such as Mobile Ad-Hoc Networks (MANETs) and Wireless Sensing Networks (WSNs).
  • Research and Educational Purposes: It is an important tool for networking research and teaching. It can be used to test and evaluate new protocols and networking concepts.

Features of NS2 in Hindi | Features of NS2:

  • Detailed Simulation: It can simulate various levels (layers) of a network, such as the physical layer, data link layer, network layer, etc.
  • Customization: Users can customize their network and protocol simulations according to their needs.
  • User-Friendly Interface: It also has a graphical user interface (GUI) for displaying and analyzing results.
  • Support for Various Protocols and Topologies: It can simulate many types of network topologies and protocols.

Purpose of NAM in Hindi |  Purpose of NAM (Network Animator):

NAM (Network Animator) is a graphical tool that helps to visualize network simulations. After a simulation in NS2, NAM is used to show the results of the simulation in a graphical format.

Purpose of NAM:

  • Visualization of Network Simulation: The main purpose of NAM is to visualize the communication and data transmission that occurs within a network. It graphically shows the journey of packets, routing, and traffic patterns.
  • Analysis of Data Transfer: NAM can be used for a detailed study of data transfer between different nodes of a network, packet drops, delay, and bandwidth utilization.
  • Study of Simulation Results: It displays the activities of different nodes during the simulation in an animated way, which makes it easy for the user to understand the simulation process.
  • Help in Research and Education: NAM is used to easily understand the results of network simulations and to present them for research or teaching purposes.

Features of NAM in Hindi | Features of NAM:

  • Animation: It shows the result of the simulation through animation, such as the movement of packets between nodes, routing, and network congestion.
  • Intuitive and User-Friendly: The interface of NAM helps users to easily understand the results of the simulation and to improve network performance accordingly.
  • Descriptive Statistics: It provides detailed statistics about packet transmission, drops, and other important metrics.

Installation Process of NS2 & NAM in Hindi | Installation Process of NS2 and NAM 

To understand the installation process of NS2 and NAM correctly and to use them successfully, it is necessary that the user has a suitable operating system (like Linux, Ubuntu). It can also be installed on Windows, but its installation and use are easier on a Linux-based operating system.

1. Installation of NS2 and NAM in Linux (Ubuntu):

Step 1: Update required packages

First, you need to update all the packages on your system. For this, open the terminal and run the following commands:

sudo apt-get update
sudo apt-get upgrade

Step 2: Install required libraries and tools

Some additional libraries and tools are required for NS2 and NAM, which need to be installed. Use the following command for this:

sudo apt-get install build-essential autoconf automake libxmu-dev

Step 3: Install NS2 and NAM

Now you can install NS2 and NAM. Use the following command for this:

sudo apt-get install ns2 nam

Step 4: Confirm installation

After NS2 and NAM are installed, you can check their version to see if they have been installed successfully. Use the following command for this:

ns
nam
If NS2 and NAM have been installed correctly, these commands will work and you will see the version number or a GUI screen.

Step 5: Run the simulation file

To start a simulation in NS2, a TCL (Tool Command Language) script is created. After creating a sample TCL file, you can run it using the following command:

ns filename.tcl
nam filename.nam

This will run the simulation and show the animation of the network simulation in NAM.

Installation of NS2 & NAM in Windows in Hindi |  Installation of NS2 and NAM in Windows:

To install NS2 on a Windows operating system, tools like Cygwin or VMware are used. Cygwin provides a simulated environment like Linux, where you can use NS2 and NAM.

Step 1: Download and install Cygwin

First, download Cygwin from its official website and install it on your Windows system.

Step 2: Install required packages

During the Cygwin installation, you will need to select the required packages, such as GCC, Make, Tcl/Tk, Perl, etc.

Step 3: Download NS2

After Cygwin, download NS2 from its official website or another source and install it on your system. Use the Cygwin command-line tools for this.
