3D ray-tracing embedded into an integrated simulator for car-to-X communications

This contribution presents a 3D ray-tracing approach which is used as one major component in an integrated simulator for car-to-X communications consisting of a road traffic, a network and a radio propagation simulator. Since the computing time for performing ray-tracing is a critical parameter for the overall performance of the integrated simulator acceleration techniques have to be applied. Results from a study to increase runtime efficiency of the ray-tracer by software and hardware acceleration techniques are presented and possible applications of the simulator are discussed.
