Poster Abstract: Concept of a Cross-Layer Design for Packet Routing in Vehicular Ad Hoc Networks

In this poster we present a cross-layer design between packet routing and medium access control (MAC) for a vehicular ad hoc network (VANET) in order to guarantee special quality of service (QoS) requirements. As precondition we consider vehicles equipped with driving- assistant-systems that exchange environmental object information through the network. By the use of wireless communication the vehicles can share their environment data and extend their environment model. This collected object information gets obsolete after some time because of the fast changing surroundings of a vehicle. Therefore it should be distributed to other vehicles with a lower delay than the data gets outdated. This introduces a special low delay QoS requirement the VANET has to provide to the application.
