Foreword
The world of mobile wireless systems has lately been transforming
dramatically, driven by technology push and market pull, and catalyzed
by the competition of the open market. In the present decade, we expect
to witness revolutionary changes in mobile computing paradigm. The
foundations for such developments have already been laid in the form of
Mobile IP (MIP). Hence, a book on the design and implementation of
MIP -based solutions is both timely and topical.
However, for a number of reasons, it is not an easy task to write
books on topics pertaining to practical mobile systems and their
synthesis. Wireless networking practices are difficult to express in an
elegant pedagogical presentation, and they become dated pretty fast.
Probably so, experts, with rare exceptions, have shown little interest in
the documentation of their professional experiences even though they
have been encountering new phenomena at their craft almost everyday.
In order to disprove this theory, Dr. Abdul Sakib Mondal has done a
remarkable job of extracting the essence of MIP and has presented the
issues, through practical examples and experience-based data, in a way
that can sustain the attention of even the busiest executive. He has been
intimately involved with MIP research at the Software Concept
Laboratory in Infosys Technologies Limited, and his experience carries
over into this entertaining book. This is a great book for MIP
professionals who have a difficult time in finding information that they
often look for but cannot find easily from literature.
In the flurry and excitement of describing a hot technology like MIP,
the tendency is to overlook minute details, which are seemingly trifle

from an analytical point of view, but are a must for practitioners. I,
therefore, am particularly pleased to find that this book does pay
attention to provide concepts and principles behind the technology, and
in some cases, the history, thus allowing a reader to appreciate the trade
offs vis-a-vis key issues. These information will be very useful to
students learning the MIP technology, system managers trying to
improve their MIP networks, and also product developers hoping to
avoid past mistakes. In fact, this book is indispensable, if you are
involved in a development project that benefits from MIP routing at any
level.
In a nutshell, there are few books on the current practices of MIP
based systems and Dr. Mondal has written a book that makes a laudable
attempt to fill this major gap. I am happy to commend this informative as
well as entertaining book to all mobile communication and computing
professionals.

Preface
Mobility of computing devices has gained significant importance in
recent years. This is enhanced by the presence of a gamut of miniaturized
portable devices and the growing popularity of mobile applications, be
they in the realm of mobile commerce or mobile entertainment. Adding
momentum to the mobility is a protocol called mobile IP.
This book is all about mobile IP. If you have ever been in a situation
in which you wanted to move with your laptop across different networks
and avoid the pain of reconfiguring it for each of these network, you will
be excited and anxious about mobile IP. Mobile IP is a solution to the
problem of allowing a mobile host to change its location without
disrupting its ongoing communication with other hosts. This book
explains how this is possible. The book proceeds to delve into the design
and implementation of mobile IP solution. As a corollary this book
explores "things" that would not be possible without mobile IP. The
description is at a level suitable for a wide section of readers - those who
want an overview, system administrators who want to get advanced
details like network management, performance and security issues.
Issues involved in deploying a mobile IP solution are discussed in great
details. This book provides information that developers often look for but
cannot find easily from literature - like what features a mobile agent
should possess, how to tackle the firewall traversal for a mobile host. The
book addresses some of the questions associated with applying mobile IP
in the real world. Specifically it discusses how Mobile IP is
administered, how Mobile IP can be integrated into existing network

management solutions, how to develop software that supports Mobile IP
and importantly what are the applications that are suited for Mobile IP.
Since the book is on mobile IP, it has deliberately left out details of
TCP/IP implementation that may be necessary to fully appreciate the
content. In a way it assumes that readers have suitable background in
TCP/IP. It also avoids implementation details at the source code level, as
things will differ from operating system to another. However, a few
important mobile IP implementations have been discussed to give a feel
of what are the things that may be involved in a mobile IP solution.
Interested readers may go through the resources provided in the
appendices to get more details on a specific implementation.
