Abstract
One of the most promising deployment areas of mobile ad hoc networks are inter-vehicle communication and road telematics. The diverse spectrum of applications requires the full range from low to high data rates. To provide broadband services with moderate terminal complexity and explore the available radio spectrum at the same time, frequency division multiple access (FDMA) should be introduced. In the FleetNet project an appropriate air-interface based on UMTS Terrestrial Radio Access Time Division Duplex (UTRA TDD) is under development. One component is the novel FDMA concept, which is introduced in this paper, and which enters an evolutionary path towards higher data rates. The concept takes into account the complexity of the hardware, the distributed character of self-organizing networks, and the efficient exploration of the scarce frequency spectrum. Simulation results for the new decentralized FDMA scheme show high and efficient utilization of available resources.Keywords
