TLDR
This paper gives a formalization of location relatedness in queries and distinguishes location dependence and location awareness and provides thorough examples to support the approach.Abstract:
The advances in wireless and mobile computing allow a mobile user to perform a wide range of aplications once limited to non-mobile hard wired computing environments As the geographical position of a mobile user is becoming more trackable, users need to pull data which are related to their location, perhaps seeking information about unfamiliar places or local lifestyle data In these requests, a location attribute has to be identified in order to provide more efficient access to location dependent data, whose value is determined by the location to which it is related Local yellow pages, local events, and weather information are some of the examples of these dataIn this paper, we give a formalization of location relatedness in queries We differentiate location dependence and location awareness and provide thorough examples to support our approachread more

Location-dependent query processing: Where we are and where we are heading
TL;DR: The technological context (mobile computing) and support middleware (such as moving object databases and data stream technology) are described, location-based services and location-dependent queries are defined and classified, and different query processing approaches are reviewed and compared.

Main Memory Evaluation of Monitoring Queries Over Moving Objects
TL;DR: Experimental evaluation establishes that indexing queries using the grid index yields orders of magnitude better performance than other index structures such as R*-trees.

Efficient Evaluation of Continuous Range Queries on Moving Objects
TL;DR: In this paper, the authors evaluate several in-memory algorithms for efficient and scalable processing of continuous range queries over collections of moving objects and present a detailed analysis of a grid approach which shows the best results for both skewed and uniform data.

Modeling and querying moving objects
TL;DR: This work proposes a data model for representing moving objects in database systems called the Moving Objects Spatio-Temporal (MOST) data model, and devise an algorithm for processing FTL queries in MOST.
