Complexity Reduction Techniques for a Frame Based Dynamic Ray Tracing Approach

Ray tracing is a simulation tool to determine propagation paths and create channels for communication applications. Mobile links or environments with moving objects, require several ray tracing simulations to create representative communication channels. This paper proposes a dynamic ray tracing approach, by utilizing a frame based technique, depicting scenarios with moving objects as sequential snapshots. However, the computational complexity and calculation times are very high without further optimization and complexity reduction. This paper analyzes and evaluates two different techniques, to accelerate the calculation time of the simulations, in order to enable a feasible framework for dynamic ray tracing. A match of 1% to 15% is observed, between the original and optimized dynamic ray tracing results, depending on the utilized technique.
