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 …

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 …

Moving object environments are characterized by large numbers of moving objects and
numerous concurrent continuous queries over these objects. Efficient evaluation of these …

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 …

In this paper we evaluate several in-memory algorithms for efficient and scalable processing
of continuous range queries over collections of moving objects. Constant updates to the …

The new generation of information technology is exchanging a huge data and these data
should be process for analytical and visualization purposes. In most of our daily activities we …

Wireless data broadcast is a promising technique for information dissemination that
leverages the computational capabilities of the mobile devices in order to enhance the …

We are witnessing in recent years growing interest for location-dependent information
services among mobile users. We examine the issue of processing location-dependent …

The emergence of location-aware services calls for new real-time spatio-temporal query
processing algorithms that deal with large numbers of mobile objects and queries. In this …

In this paper, we propose, SCUBA, a S calable C lu ster B ased A lgorithm for evaluating a
large set of continuous queries over spatio-temporal data streams. The key idea of SCUBA …
