Future intelligent transport systems will be based on digital networking of vehicles and infrastructure for mutual information exchange. This will enable many new applications to increase traffic safety and efficiency as well as new comfort services. How digital networking should look in concrete terms is now being researched from different directions. The basis will be wireless communication systems. So much is clear. However, there are mainly the two possibilities of ad hoc networks with

The present paper examines heterogeneous solutions in which both communication systems exist. Accordingly, it is possible for the two communication systems to complement each other sensibly in certain scenarios in order to fill corresponding technological gaps. In principle, the various applications also have different characteristics and requirements for communication technology. For example, in traffic safety and efficiency applications there is an information exchange between many endpoints, while personal comfort applications are generally limited to two points, the client and the server. Tolerable communication latencies are more strict for security than for efficiency applications and so on. For these reasons, this work begins with a classification of planned "Day One" applications and current application trends. In addition, a technical assessment metric is introduced, in particular to enable the comparison of the mobility-related applications. The main part of this thesis deals with the simulative comparison of heterogeneous ad hoc and cellular communication approaches. The V2X Simulation Runtime Infrastructure (VSimRTI) is improved and expanded in different ways. Since the modeling of the radio signal propagation has a great influence on the communication characteristics for ad hoc networks, the simulation environment is extended. On the one hand, an approach to the deterministic simulation of buildings and their sh [...]
