Voronoi-Based K Nearest Neighbor Search for Spatial Network Databases

Summary: Introduces a first-order Voronoi decomposition for spatial-network KNN, precomputing intra-region distances and only border-to-border inter-region distances to avoid global shortest-path materialization. Outperforms online and index-based methods by up to 10×, with 4× higher filter selectivity. (summarized by gpt-5.6-luna on Jul 24 2026)
