An Introduction to Network Modeling and Simulation for the Practicing Engineer (1118063643) cover image
This book provides the practicing engineer with a concise listing of commercial and open-source modeling and simulation tools currently available including examples of implementing those tools for solving specific Modeling and Simulation examples. Instead of focusing on the underlying theory of Modeling and Simulation and fundamental building blocks for custom simulations, this book compares platforms used in practice, and gives rules enabling the practicing engineer to utilize available Modeling and Simulation tools. This book will contain insights regarding common pitfalls in network Modeling and Simulation and practical methods for working engineers.

“This book provides principles, guidelines, and the do’s and don’ts for practical use of the art of modeling and simulation. The authors have many years of experience in the field and are insightful with their assessment of a very important engineering discipline. The book can be used for guidance and learning “best practices” on M&S as it covers very broad areas in all key protocols layers of communications. The authors also pointed out many subtleties of M&S, which are easily overlooked by many practitioners. This is a must-read book for program managers who make decisions about setting scope, considering tradeoffs, and defining metrics, before committing to a M&S project.”
