Location-based spatial queries (LBSQs) refer to spatial queries whose answers rely on the
location of the inquirer. Efficient processing of LBSQs is of critical importance with the ever …

Today's Internet is incapable of handling information like a stop sign. Such information stays
in a geographic region, consistently beams to the people who move into from certain …

Spatial queries such as range query and kNN query in road networks have received a
growing number of attention in real life. Considering the large population of the users and …

Shortest path computation is one of the most common queries in location-based services
that involve transportation networks. Motivated by scalability challenges faced in the mobile …

A continuous nearest neighbor (CNN) search, which retrieves the nearest neighbors
corresponding to every point in a given query line segment, is important for location-based …

In a wireless mobile environment, data broadcasting provides an efficient way to
disseminate data. Via data broadcasting, a server can provide location-based services to a …

Wireless broadcast provides a scalable and secure spatial data dissemination approach for
geographical applications in wireless mobile environments. Among various location-based …

In this paper, we investigate the problem of processing generalized k-nearest neighbor
(GkNN) queries, which involve both spatial and non-spatial specifications for data objects, in …

To increase the scalability of location-based services (LBSs), researchers have begun to
propose methods for processing spatial queries in wireless broadcast environments. In this …
