Voronoi-Based K Nearest Neighbor Search for Spatial Network Databases

Summary: Voronoi-based KNN search for spatial networks using first-order Voronoi diagrams to partition the network and precompute intra- and inter-region distances. By localizing precomputation to regions and restricting cross-region work to border points, it achieves up to 10x faster KNN queries and ~4x better filter selectivity than online or index-based approaches.
