Abstract. The need for location-based services has motivated an important research effort in the efficient processing of location-dependent queries. Most of the existing approaches...
Existing approaches for the processing of location-dependent queries implicitly assume location data expressed at maximum precision (e.g., GPS). However, there exist applications w...
Location-based services have attracted the attention of important research in the field of mobile computing. Specifically, different mechanisms have been proposed to process loc...
In location-based services, it is common for a user to issue a query based on his/her current position. One such example is "find the available cabs within two miles of my cu...
Client side caching of location dependent queries is an important technique for improving performance of location-based services. Most of the existing research in this area has fo...
