Modeling and Simulation of Distributed Fog Environment Using <scp>FogNetSim</scp> ++

Processing data at the cloud, generated from millions of IoT devices is not beneficial in terms of energy and communication cost. Many researchers have proposed several techniques to utilize cloud resources efficiently; however, the processing of massive data at the cloud not only consumes network resources such as network bandwidth but also affect other user services. To support delay-sensitive applications, the concept of fog computing is introduced. Fog computing extends the computing, storage, and network services closer to the source. The existing fog simulators are mostly focused on sensors and broker nodes. However, the network, context-aware, and mobility features are properly explored in the simulators. In this chapter, we provide a step-by-step guide to configure and explore the FogNetSim++ environment. The FogNetSim++ covers the network aspects such as delay, packet error rate, transmission range, handover, scheduling, and heterogeneous mobile devices. The chapters are organized as follows. The concept of fog computing is discussed in Section 11.1. Section 11.3 covers the concept of Modeling and Simulation. The FogNetSim++ architecture is covered in Section 11.4. Section 11.5 covers the Installation guide and sample test simulation. Finally, the conclusion is presented at the end.
