Beschreibung

The rapid evolution of wireless technology has made people's needs for communication and access to information grows even faster. The fact that anyone can be reached at any time and any place has become extremely convenient, for some it as even become mandatory. The advent of the Internet has made any information easily accessible and we now expect the same on-the-go.

Wireless communications have been in constant evolution for the past few years, the best known example being cellular networks which provide people with communication services along with the freedom of movement. Unfortunately physical constraints that arise when working with wireless technology make it difficult to provide such services everywhere, especially indoors.

This text book is written in simple and easily understandable language. I (Dr.Prakash Kumar)made sincere attempt to analyze every topic completely and put before the readers of this book in the best presentable form. The book covers all the syllabus of the subject 'Mobile Ad-Hoc Networks' for UG and PG students of Computer Science. from the basic to advance points

 Preface

The rapid evolution of wireless technology has made people's needs for communication and access to information grows even faster. The fact that anyone can be reached at any time and any place has become extremely convenient, for some it as even become mandatory. The advent of the Internet has made any information easily accessible and we now expect the same on-the-go.

Wireless communications have been in constant evolution for the past few years, the best known example being cellular networks which provide people with communication services along with the freedom of movement. Unfortunately physical constraints that arise when working with wireless technology make it difficult to provide such services everywhere, especially indoors.

This text book is written in simple and easily undestandable language. I made sincere attempt to analyze every topic completely and put before the readers of this book in the best presentable form. The book covers all the syllabus of the subject 'Mobile Ad-Hoc Networks' for UG and PG students of Computer Science. from the basic to advance points.

All the topic have been illustrated with suitable diagram for easy understanding.All the efforts have been made to bring out a very good and useful book. Neverthless, the author does not lay any claim to perfection,there is always scope for improvement in a book of this kind.

All suggestions for its improvement will therefore be welcomed.

INTRODUCTION

1.1 Overview

A mobile ad hoc network (MANET) is a continuously self-configuring, infrastructure-less network of mobile devices connected without wires. Ad hoc is Latin and means "for this purpose".

Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. They may contain one or multiple and different transceivers between nodes. This results in a highly dynamic, autonomous topology.

MANETs are a kind of Wireless ad hoc network that usually has a routable networking environment on top of a Link Layer ad hoc network. MANETs consist of a peer-to-peer, self-forming, self-healing network in contrast to a mesh network has a central controller (to determine, optimize, and distribute the routing table). MANETs circa 2000-2015 typically communicate at radio frequencies (30 MHz - 5 GHz).
