Location Dependent Query Processing
The continuous development of wireless networks and mobile devices has
motivated an intense research in mobile data services. The advances in wireless
and mobile computing allow a mobile user to perform a wide range of applications
once limited to non-mobile hard wired computing environments. As the
geographical position of a mobile user is becoming more tractable, users need
to pull data which are related to their location, perhaps seeking information about unfamiliar places or local lifestyle data. In these requests,
a location attribute has to be identified in order to provide more efficient
access to location dependent data, whose value is determined by the location to
which it is related. Local yellow pages, local events, and weather information
are some of the examples of these data. There are several methods to process
these data.
Location of an object or a person is its geographical position on the earth
with respect to a reference point. This information can be characterized by
using a number of different representations including
latitude/longitude/altitude or street addresses, etc. and by giving
granularity, accuracy and rate of change (velocity). With the technological
advances in cellular communications and sensing appliances, location of people
has become more realtime and tractable. Location representation may include
timestamp information as it may be related to a moving object/person, and may
be represented in various ways.
