Abstract |
|
A proxy-based approach to continuous nearest neighbor search query and window queries has been implementing in this paper and get a better result over mobile environment. The proxy creates estimated valid regions for mobile clients by exploiting spatial and temporal locality of spatial queries. For Nearest Neighbor queries, to devise two new algorithms to accelerate Estimated Valid Region growth, leading the proxy to build effective Estimated Valid Regions even when the cache size is small. On the other hand, to propose to represent the Estimated Valid Regions of window queries in the form of vectors, called estimated window vectors, to achieve larger estimated valid regions the above techniques developed for .net application and display for better result, efficient output in spatial search in around nearest location based on spatial queries. |
