| Abstract: | With the proliferation of wireless communications and the rapid advances in technologies for tracking the positions of continuously moving objeets,algorithms for efficiently answering queries about large numbers of moving objects increasingly are needed.This paper proposes an algorithm for answering RNN queries for continuously moving objects in the plane .As a part of the solution to this problem and as a separate contribution,an algorithm for answering N(?) queries for continuously moving points is also proposed. |

| Keywords: | moving objects nearst neighbor queries reverse nearest neighbor queries |
