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 …

In this paper, we study the problem of continuous monitoring of reverse k nearest neighbors
queries in Euclidean space as well as in spatial networks. Existing techniques are sensitive …

Given a positive value r, a distance-based range query returns the objects that lie within the
distance r of the query location. In this paper, we focus on the distance-based range queries …

With the proliferation of mobile devices, an increasing number of urban users subscribe to
location-based services. This trend has led to significant research interest in techniques that …

Recently, NAND flash memory has been one of the best storage mediums for various
embedded systems such as MP3 players, mobile phones and laptops because of its shock …

Query processing in road networks has been studied extensively in recent years. However,
the processing of moving queries in road networks has received little attention. In this paper …

The cost of monitoring and kee** the location of a Moving Query updated is very high, as
the calculation of the range query needs to be re-evaluated whenever the query moves …

This paper proposes a content-based video indexing system which provides the
functionalities necessary for automatic management of video data through integration of …

In this paper, we study Resource Constrained Best Upgrade Plan (BUP) computation in road
network databases. Consider a transportation network (weighted graph) G where a subset of …
