Cooperative intelligent transport systems (C-ITS) are getting more and more used in the automotive industry. There are certain types of communication going on like vehicle to vehicle (V2V), vehicle to infrastructure (V2I), or to any relevant participant of the traffic, vehicle to everything (V2X). Before applying C-ITS solutions in real world situations, a careful checking is nessesary for ensuring security. The subject of this thesis is a simulator environment which can handle numerous arbitrarily configured ITS stations. The throughput of the thesis will be a software with GUI. The user can place waypoints to set the route of a simulated station, and the location of the simulator. After this the program generates a TX power for each GPS point in the simulated route, as they come from the moving station, not the stationary simulator. The user can set the speed values on a histogram and refine the TX data alike. The output is an NMEA or JSON formatted file, with GPS data and the custom TX power data. This file can act as the input of the V2X simulation environment. The novelty of this solution is that apart the route that it can simulate the fluctuating of the distance to the radio station. This method can create a much more realistic environment than the currently available simulators.
