The DYMO Routing Protocol in VANET Scenarios

Coupling Vehicular Ad Hoc NETworks (VANETs) with wired networks such as the Internet via access points creates a difficult mix of highly mobile nodes and a static infrastructure. In order to evaluate the performance of typical ad hoc routing protocols - in particular, the authors used DYnamic MANET On Demand (DYMO) - in such VANET scenarios, they combined micro-simulation of road traffic and event-driven network simulation. Thus, they were able to analyze protocols of the Internet protocol suite in VANET scenarios with highly accurate mobility models. Varying parameters of DYMO for a multitude of traffic and communication scenarios helped point out approaches for improving the overall performance and revealed problems with the deployment.
