They include application (traffic) models, link abstraction models, mobility models, and contact traces. We discuss each of them individually, which concrete models exist, and how they work in general. Furthermore, we discuss possible techniques to speed up simulation.enApplication models | Contact traces | Link abstraction models | Mobility models | Opportunistic networks | Simulation models | Simulation speedup | Traffic models | User behavior modelsTechnology::600: TechnologyBook Part10.1007/978-3-031-47866-6_6Book Chapter
