The future transportation systems are expected to be revolutionized by connected and fully automated vehicles, significantly improving road safety and traffic efficiency, together with the overall user experience. These vehicular applications come at a high deployment cost and with a complexity that makes it necessary to be extensively tested and analyzed with simulation tools. This thesis puts its basis on an open-source vehicular network simulation framework built on the ns-3 simulator and making use of SUMO (Simulation of Urban MObility) to manage the mobility. This framework, called MS-VAN3T, enables the creation of vehicular scenarios and models all the aspects of the communication among the various entities in the created scenarios.
