Introduction to Network Modeling and Simulation for the Practicing Engineer

Jack L. Burbank leads the Wireless Networking section within the Communications and Network Technologies group of The Johns Hopkins University Applied Physics Laboratory (JHU/APL). Mr. Burbank is an expert in the areas of wireless networking and modeling and simulation, focusing on the application and evaluation of wireless networking technologies to the military context. His team of network engineers at JHU/APL participates within the Internet Engineering Task Force (IETF) and the IEEE 802 standards organization. Mr. Burbank is a professor of networking and telecommunications in The Johns Hopkins University Part-Time Engineering Program, and is a member of the IEEE and ASEE. William T. Kasch received a B.S. in Electrical Engineering at the Florida Institute of Technology in 2000 and an M.S. in Electrical and Computer Engineering at the Johns Hopkins University in 2003. His interests include various aspects of wireless networking, including MANET, IEEE 802 technology, and cellular. He participates actively in both the IEEE 802 standards organization and the Internet Engineering Task Force.Jon R. Ward works in the wireless networking section of the communications and networking technology (VCT) group at The Johns Hopkins University Applied Physics Laboratory (JHU/APL) in Laurel, MD. He has worked projects focusing on network design and interference testing of standards-based wireless technologies such as IEEE 802.11, IEEE 802.15.4, and IEEE 802.16.

"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."—Richard Lau, Chief Scientist and Telcordia Fellow, Telcordia Technologies
