This is the book that the simulation industry is missing This is an introduction and reference for Real-Time Distributed Simulation. Distributed Simulation is the term describing connecting people, equipment and simulators together in a synthetic environment. If you are involved with any type of simulator and want to connect it to another system, then you need to have this book. The book describes terrain in simulation, 3-D model structure, Simulator Qualification Levels, Distributed Interactive Simulation (DIS), High Level Architecture (HLA), Validation, Verification and Accreditation (VV&A) as well as providing a methodology and process for planning and implementing a Distributed Simulation project. The book also provides an invaluable Distributed Simulation Agreements Template. This is a very useful book for anyone involved with distributed simulation and was written by someone that has spent nearly 20 years in the industry: building simulators and connecting them to other simulators.
