What is NS2 in computer?

Network Simulator 2 (NS2) provides substantial support for simulation of different protocols over wired and wireless networks. It provides a highly modular platform for wired and wireless simulations supporting different network elements, protocols, traffic, and routing types [20].

What is the application of NS2?

NS-2 can be used to implement network protocols such as TCP and UPD, traffic source behavior such as FTP, Telnet, Web, CBR, and VBR, router queues management mechanism such as Drop Tail, RED, and CBQ, routing algorithms, and many more.

How does a network simulator work?

In computer network research, network simulation is a technique whereby a software program replicates the behavior of a real network. This is achieved by calculating the interactions between the different network entities such as routers, switches, nodes, access points, links, etc.

What is queue limit in Ns2?

Each node uses a DropTail queue that has a maximum size of 10.

How do I start Ns2?

How to Run NS2 Program in Linux

  1. Source code for main file. Store the main source file with the filename without any whitespaces, and also stored in the folder name without any whitespaces.
  2. Open the terminal and verify the installed package.
  3. Change the location.
  4. Execute the main file.
  5. Get the simulation.

What are the features of Ns2?

Features of NS2 :

  • It’s a networking research discrete event simulator.
  • It has a lot of features for simulating protocols including TCP, FTP, UDP, HTTPS, and DSR.
  • It is capable of simulating both wired and wireless networks.
  • It is mostly based on Unix.
  • Its scripting language is TCL.

What is null agent in NS2?

A “null” agent frees the packets received. An “FTP” and a “CBR” traffic generator are respectively attached to “TCP” and “UDP” agents, and the “CBR” is configured to generate 1 Kbytes packets at the rate of 100 packets per second. FTP will automatically control the traffic according to the throttle mechanism in TCP.

What is TCP in NS2?

TCP/IP communications can appear to be daunting at first. It is actually a very simple communication tool. It defines the details of how data is sent and received through network adapters or hubs. Transmission Control Protocol (TCP) makes sure all packets arrive safely.

What is TCP in Ns2?

What is Ns2 Javascript?

The improved version of Netscript that allows users to write full-fledged Javascript code in their scripts, while still being able to access the Netscript functions. ns2 was developed primarily by Github user jaguilar.

What are advantages of NS2?

NETWORK SIMULATOR-2 It has many advantages that make it a useful tool, such as support for multiple protocols and the capability of graphically detailing network traffic. Additionally, NS2 supports several algorithms in routing and queuing. LAN routing and broadcasts are part of routing algorithms.

What is NS2 (Network Simulator Version 2)?

1. What is NS2 NS2 stands for Network Simulator Version 2. It is an open-source event-driven simulator designed specifically for research in computer communication networks. 2. Features of NS2

What are the features of NS2?

Features of NS2 1. It is a discrete event simulator for networking research. 2. It provides substantial support to simulate bunch of protocols like TCP, FTP, UDP, https and DSR. 3. It simulates wired and wireless network. 4. It is primarily Unix based.

How to be a beginner in ns-2?

To be a beginner in NS2, you must know two major aspect of NS-2 i.e. the programming language also used in NS2 and the basic tools used in NS-2.Ns2 can code also using C++ and TCL. In this article, we also have emphasize on the basic requirement of NS-2, without which also simulation is not possible in NS-2.

What programming language is used in ns2?

3. Basic Architecture NS2 consists of two key languages: C++ and Object-oriented Tool Command Language (OTcl). While the C++ defines the internal mechanism (i.e., a backend) of the simulation objects, the OTcl sets up simulation by assembling and configuring the objects as well as scheduling discrete events.
