We propose in this paper a design of the proxy supporting nearest-neighbor queries. We also propose several algorithms to create and extend estimate valid regions. An estimate valid regions degradation algorithm and a cache replacement policy are proposed to reclaim cache space when the cache space is insufficient. To evaluate the performance of the proposed architecture and algorithms, several experiments...
