Evaluation of Routing Protocols for Vehicular Ad Hoc Networks in Typical Road Traffic Scenarios

Vehicular multi-hop ad hoc networks (VANETs) enable the exchange of information between vehicles without any fixed infrastructure. The application range of such networks may cover safety related applications like the warning of drivers about accidents or congestions as well as Internet access e.g. via gateways along the road. The varying conditions in VANETs introduce high requirements on the routing protocols being used. Thus, we developed a realistic freeway mobility model and evaluated the performance of AODV, DSR, FSR and TORA in typical freeway traffic scenarios on the basis network simulations. The results show that AODV performs best in most of the simulated traffic situations, followed by FSR and DSR, while TORA is inapplicable for VANETs.
