Abstract: In view of the shortage of exisiting reverse nearest neighbour(RNN)query method in road network,NVD-RNN algorithm making use of network Voronoi diagram(NVD) has good effect.The algorithm divides the road network into small Voronoi regions and adopts two processes:filtering and refining processes.The filtering process mainly stores possible query results in advance.The major task of refining process is to find query results from potential outcome sets,in addition it provides ADDNVD-RNN algorithm to dispose of newly increased points and DENVD-RNN algorithm to cope with deleted points any further.The experiment demonstrates that the algorithm has obvious advantages in dealing with reverse nearest neighbor in road network.

Key words: Network Voronoi diagram,Reverse nearest neighbor query,Road network environment
