What this book covers
Chapter 1, Getting Started with Network Simulator-3 (ns-3), looks at how, before starting to use ns-3 for simulations, it is very important to learn how to use ns-3 as a simulation tool for development, testing, and evaluation activities. This chapter mainly discusses ns-3 and its supporting tools’ installation for implementation and executing simulations. To make the aforementioned activities simple, ns-3 users must learn about the installation of ns-3, supporting animation tools to quickly visualize simulations, and how to write ns-3 simulation programs easily using an editor. Although the ns-3 documentation provides these details, it is difficult to follow for beginners and takes many hours to complete these activities. We explain these activities in simple steps to complete them quickly.
Chapter 2, Monitoring, Debugging, Tracing, and Evaluating Network Topologies in ns-3, discusses how to use ns-3 logging features to display simulation details such as nodes and their configuration details, protocol behavior, and events at various levels for informative simulations. Besides this, to understand simulation errors, exceptions, and abrupt events, ns-3 debugging and tracing features are discussed in detail. Finally, it is very important to evaluate test scenario performance in terms of throughput, delay, jitter, and packet loss metrics. In this regard, to help you, this chapter discusses how to use ns-3 FlowMonitor or evaluate test scenarios.
