Abstract

An innovative adaptive mesh strategy based on LOLA-Voronoi (Local Linear Approximation-Voronoi) is proposed to efficiently predict indoor signal propagation. This indoor high-efficiency propagation model (HPMO) can identify nonlinear regions to capture the complex behavior and achieve sufficient prediction accuracy when the computational cost is limited. A set of representative reference scenario simulation settings and results are reported and discussed to analyze the accuracy, and the efficiency of HPMO. Comparison with the original model based on traditional uniform mesh shows that the proposed method herein yields a considerable reduction in the prediction calculation cost of the complex indoor environment, while maintaining sufficient accuracy.
