Network Simulator (NS2) (40 hours)

What’s the course about

A computer network is a telecommunications network that allows computers to exchange data. The connections between computers are established using either cable or a wireless media. The best-known computer network is the Internet. Today, the computer networks - including LAN and WAN - have become too complex that we need software tools to understand their behavior.

The software tools simulate events for us to analyze the behaviour of the networks. NS, standing for Network Simulators, is an open source, simulation software. The course is about using NS2, the second version of NS, to simulate networking protocols (like TCP, FTP, UDP, HTTP and DSR); wired and wireless networks.



Course objectives

This course gives an introduction to the basics of networking, working principle of protocols like TCP & UDP, and the two key languages: C++ and Object-oriented Tool Command Language (OTcl) used in NS2. The course helps students master the concept of routing for sending the data from one node to another node, evaluating the results through trace analysis as well as graphical visualization. Students are trained to edit & create protocols for new models and support for simulation of TCP, routing, and multicast protocols over wired and wireless networks.

Key course content

  • Introduction to Basic Networks and Network Simulation
