A PARALLEL APPROACH FOR 3D RAY-TRACING TECHNIQUES IN THE RADIO PROPAGATION PREDICTION
Keywords:
Parallel computing, Cluster of PC'sAbstract
A computational parallel approach for 3D ray-tracing techniques in the radio propagation prediction is presented. This approach considers that the main tasks in a 3D ray-tracing technique can be evaluated in an independent and/or parallel way. The workload distribution among the participant nodes of the parallel architecture (cluster of PC's) is performed through a random assignment of the initial rays and the field points for them. Simulations are realized in order to validate and evaluate the performance of the proposed model.
