On Dynamic Ray Tracing and Anticipative Channel Prediction for Dynamic Environments

Ray tracing algorithms, that can simulate multipath radio propagation in presence of geometric obstacles such as buildings, objects or vehicles, are becoming quite popular, due to the increasing availability digital environment databases and high-performance computation platforms, multicore computers cloud computing services. When vehicles moving, which is case industrial vehicular environments, multiple successive representations ("snapshots") ray runs often necessary, require a great human effort deal resources. Recently, Dynamic Tracing (DRT) approach has been proposed predict evolution within given time lapse on base current geometry, assuming constant speeds and/or accelerations for moving objects, using analytical extrapolation formulas. This done without re-running full every "snapshot" environment, therefore with saving. DRT embedded mobile system used real-time, ahead-of-time (or anticipative) field prediction possible opens way interesting applications. In present work, full-3D algorithm presented allows account reflections, edge diffraction diffuse scattering general where translate rotate. For purpose validation, model first applied some ideal cases then realistic results compared conventional simulation measurements available literature.
