Inter Vehicle Communication (IVC) has become a major topic during the last few years. Within the FleetNet project a novel mobile ad hoc network will be developed – based on the UMTS Terrestrial Radio Access Time Division Duplex (UTRA TDD) air-interface – to interconnect vehicles and roadside gateways via a mobile Internet. In this paper we focus on the impacts of vehicular traffic dynamics on protocols for ad hoc networks, specifically the medium access, which supports QoS by means of resource reservation. Based on analytical distributions of vehicular traffic theory and on realistic traffic scenarios we develop requirements and dependencies of the developed protocols for ad hoc networks. From the results it can be concluded that the proposed modified MAC scheme based on UTRA TDD can cope with typical network topology changes as expected for vehicular environments.
