Introduction to Network Simulator NS2
Spurred by a dearth of information on NS2 during their graduate studies, the authors have written this primer on the open-source simulation software to help subsequent generations of students grapple with the program and its uses. NS2, an event-driven sim

Preface
Motivation for Writing This Book First of all, we would like to thank you for your interest in this book. This book was motivated by our frustration when we were graduate students. We were pushed to work with NS2, when we did not know what to do. We looked over the Internet, but, at the time, there were very little material on the Internet. We posted our question on every mailing list, every online forums we can think of. We did not find most of what we were looking for. We spent days and nights on many operating systems just to make NS2 run on one of the systems we have. We spent an endless amount of time, trying to understand the way NS2 moves a packet from one node to another. We did not succeed. So we were running out of time we pushed out and submitted our project/thesis as it was. Our program was as good as it was necessary to close the project. We were not satisfied with our knowledge about NS2. After the graduation, we revisited NS2 and tried to understand it more. Bits by bits, we began to understand how NS2 does a certain thing, but perhaps more importantly why NS2 does so. From our experience, it takes months, if not years, to truly understand NS2. We would not be surprised if our story above sounds particularly familiar to you. In fact, we expected you to experience a part, if not all, of our unpleasant experience. We wrote this book to ease your pain caused by NS2. We hope that this book can reduce your NS2 learning curve from years to months, or
