CONTENTS

This book is intended to help students understand certain practical aspects of computer networking. We focus on simulation of basic computer networking protocols for a deeper understanding of the workings of the protocols as well as for performance evaluation. We have also included socket programming taught at the undergraduate level to help students develop skills for network programming. Considering that students may have widely different backgrounds, we have included certain basics of networking to make the book self-contained. However, the introductory treatment on networking issues is given as a refresher of the basic concepts involved, and thorough learning of the relevant concepts from a networking book is a necessity before this book can be used.

It is well accepted that the knowledge acquired from a theoretical reading, especially in a subject such as computer networking, is incomplete when not accompanied by hands-on practice. The book is sprinkled with examples of simulations of both wired and wireless networking protocols. The assignments have been designed to be suitable for undergraduate and postgraduate levels of learning. For the advanced learner, suitable hints have been provided throughout the text to develop the skills for evaluation of new protocols.

Salient Features

(i) Emphasis on implementation and simulation of real-world network protocols.

(ii) Covers a wide ranging set of topics, starting from certain basic operating system commands to socket programming, wired network simulation, wireless network simulation, performance evaluation, and visualization.

(iii) Plenty of example programs have been provided (around ninety odd programs and scripts along with their explanations and outputs). Also many exercises (both theory and programming) requiring investigation and application of the learned concepts have been provided across all the chapters for practice.

(iv) We have tried our best to explain the concepts using simple language and analogies.

Content & Structure

Discusses the evolution of data communication techniques and the fundamental issues associated with performance evaluation. It then provides an overview of simulation and other performance evaluation techniques.

Introduces computer network protocols along with TCP/IP and OSI models. It also provides a brief overview of the networking devices used.

Explains a socket and its use in network programming. This gives an idea of developing network applications using C and socket API.

Introduces the NS2 network simulator, and exhibits the internal architecture of NS2 and its constituent software packages. It also provides pointers to installation of the package in different operating systems.

Provides basic knowledge about simulation using NS2. It elaborates on the use of Tcl and OTcl scripts along with an introduction to AWK scripting and plotting with Gnuplot.

Deals with the simulation of wired networks in detail. It shows how to simulate different protocols in different layers.

Deals with the simulation of wireless networks in detail. It also discusses the idea of simulation, very large networks and measuring the various network parameters and plotting them in suitable graphs.
