With the rapid advances of wireless communication and sensor technologies, spatial queries on moving objects are increasingly important in many sensor applications. One of the most frequently used spatial queries is the reverse nearest neighbor (RNN) query that returns the objects whose nearest neighbor is the query object. RNN answers are particularly essential to the users who are under emergency circumstances. In this paper, we propose an incremental RNN search (IRS) method to answer RNN… CONTINUE READING
