The increasing use of location-aware devices has led to an increasing availability of
trajectory data. As a result, researchers devoted their efforts to developing analysis methods …

This paper surveys indoor spatial models developed for research fields ranging from mobile
robot mapping, to indoor location-based services (LBS), and most recently to context-aware …

Moving Objects Databases is the first uniform treatment of moving objects databases, the
technology that supports GPS and RFID. It focuses on the modeling and design of data from …

This paper intoduces the Scalable INcremental hash-based Algorithm (SINA, for short); a
new algorithm for evaluting a set of concurrent continuous spatio-temporal queries. SINA is …

Given a set of objects P and a query point q, ak nearest neighbor (k-NN) query retrieves the
k objects in P that lie closest to q. Even though the problem is well-studied for static datasets …

In this article, we present a new privacy-aware query processing framework, Capser*, in
which mobile and stationary users can obtain snapshot and/or continuous location-based …

This paper proposes a generic framework for monitoring continuous spatial queries over
moving objects. The framework distinguishes itself from existing work by being the first to …

Recent research has focused on continuous monitoring of nearest neighbors (NN) in highly
dynamic scenarios, where the queries and the data objects move frequently and arbitrarily …

Web users and content are increasingly being geopositioned. This development gives
prominence to spatial keyword queries, which involve both the locations and textual …

The continuous development of wireless networks and mobile devices has motivated an
intense research in mobile data services. Some of these services provide the user with …
