A crucial step in designing communication systems is estimating their performance, particularly for complex or dynamic systems, making network simulation essential. This book emphasizes tools, modeling principles, and advanced models for discrete-event based network simulations, the standard method for evaluating new network designs. It focuses on two main simulation engines: OmNet++ and ns-3, addressing parallelization, software integration, and hardware simulations. The modeling sections are divided into wireless and higher layers. The wireless section discusses key modeling principles for the physical layer, link layer, and wireless channel behavior, featuring detailed models for IEEE 802.11 and IEEE 802.16. The higher layers section presents classical modeling approaches for the network, transport, and application layers, alongside methods for peer-to-peer networks and various topologies. Additionally, it includes catalogs of model implementations for numerous simulation engines. Targeted at master’s and PhD students in computer science and electrical engineering, as well as researchers and practitioners in academia and industry, this book serves those engaged in network simulation across all protocol stack layers.
