In this chapter, we perform a study of the existing tools for the evaluation of Fog/Edge infrastructures. First, we analyze the state of the art in the simulation of Fog/Edge infrastructures and determine the main challenges in simulation and modeling such infrastructures. Then, we use a scientific methodology to identify the most important simulation and emulation tools, identifying their main characteristics, and define a classification. Each tool is then described in detail, and compared with the others. Finally, we conclude the chapter with a discussion about future research directions in the area.
