| Abstract: | This paper addresses the problem of Group K-Nearest Neighbors (GKNN) queries in spatial network databases, and suggests a novel approach based on real network distances.
This approach essentially uses network Voronoi diagram properties together with a progressive incremental network expansion
for determining the inner network distances that are needed to obtain GKNN queries.
