Christoph Sommer, "Untersuchung von Ad Hoc Kommunikation in VANETs," Master's Thesis, Department of Computer Science, Friedrich–Alexander University of Erlangen–Nuremberg (FAU), November 2006. (Advisor: Falko Dressler)


Coupling Vehicular Ad Hoc Networks (VANETs) with wired networks via access points creates a difficult mix of highly mobile nodes and static infrastructure. In order to evaluate the performance of the new MANET routing protocol DYMO in realistic VANET scenarios using unmodified protools of the Internet protocol suite, tools for network simulation and simulation of road traffic were coupled. Modeling a multitude of probable communication patterns and traffic scenarios on a typical highway and varying parameters of DMO helped point out approaches for improving the overall performance and revealed problems with the deployment of protocols notadapted for the use in VANETs. It can be shown that in realistic scenarios even for medium densities of active nodes and low network load, overload behavior leads to a drastic decrease of the perceived network quality. Using transport and routing protocols that can act both on problems observed by lower layers and on requirements specified by higher layers therefore seems highly advisable.
