Realistic simulation of Inter-Vehicle Communication (IVC) protocols is one of the main challenges in the Vehicular Ad Hoc Network (VANET) research domain. In the scope of this project, we investigate the need for bidirectional coupling of network and road traffic simulation for more realistic simulation experiments. Incident detection, e.g. traffic jam and accident detection, for optimized route planning, as well as future safety applications, e.g. enhanced lane and distance control, are the dominant drivers for the development of adequate IVC protocols.

We developed a special simulation framework that provides coupled network and road traffic simulation using well-established simulators from both communities. In particular, we employ OMNeT++, a simulation environment free for academic use, to model realistic communication patterns of VANET nodes. Traffic simulation is performed by the microscopic road traffic simulation package SUMO.

Both domains' models are bi-directionally coupled and simulations performed on-line. This way, not only the influence of road traffic on network traffic can be modeled, but also vice versa. In particular, the influences of IVC on road traffic can be modeled and complex interactions between both domains examined.
