Fog computing supports the deployment of IoT applications closer to their (human or machine) end-users. CISCO FogDirector is a tool that can be used to manage the entire life-cycle of IoT applications over Fog infrastructures by relying on RESTful APIs. This thesis presents a prototype simulation environment, FogDirSim, which is compliant to FogDirector APIs. FogDirSim permits comparing different application management policies according to a set of well-defined performance indicators (viz., uptime, energy consumption, resource usage, type of alerts) and by considering probabilistic variations and failures in the underlying infrastructure. Lifelike motivating examples are used to validate the prototype and to show its usefulness in selecting the best application management policy.
