This paper tackles a major privacy concern in current location-based services where users
have to continuously report their locations to the database server in order to obtain the …

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 …

The wide spread of location-based services results in a strong market for location-detection
devices (eg, GPS-like devices, RFIDs, handheld devices, and cellular phones). Examples of …

In recent years, a new class of applications has come to the forefront {p-marily due to the
advancement in our ability to collect data from multitudes of devices, and process them e …

This paper presents a novel algorithm for Incremental and General Evaluation of continuous
Reverse Nearest neighbor queries (IGERN, for short). The IGERN algorithm is general as it …

The tremendous increase in the use of cellular phones, GPS-like devices, and RFIDs results
in highly dynamic environments where objects as well as queries are continuously moving …

We present a data model for tracking mobile objects and reporting the result of queries. The
model relies on a discrete view of the spatio-temporal space, where the 2D space and the …

This paper presents the scalable on-line execution (SOLE) algorithm for continuous and on-
line evaluation of concurrent continuous spatio-temporal queries over data streams …

The explosive growth of location-detection devices, wireless communications, and mobile
databases has resulted in the realization of location-based services as commercial products …

This chapter presents different spatiotemporal data management models, challenges and
future direction of spatiotemporal research. The spatiotemporal data model and analysis …
