Location-based spatial queries [PDF]
Proceedings of the 2003 ACM SIGMOD international conference on Management of data, 2003 In this paper we propose an approach that enables mobile clients to determine the validity of previous queries based on their current locations. In order to make this possible, the server returns in addition to the query result, a validity region around the client's location within which the result remains the same.
