Location-Aware Scheduling With Minimal Infrastructure [link]Paper  abstract   bibtex   
Mobile computers often benefit from software which adapts to their location. For example, a computer might be backed up when at the office, or the default printer might always be a nearby one. In many existing systems, location-triggered actions are only possible for specific applications or with special infrastructure. This paper describes \emphlcron, a system which supports \emphuser-configurable actions triggered on \emphchange in location or other events common to mobile computers. Key features of \emphlcron are its use of existing clues for location information and mapping low-level location information into user-sensible terms. \emphLcron uses a number of existing sources of location such as network connection and base station ID, allowing it to work without special hardware or GPS receivers. We map sources of low-level information such as IP address and latitude/longitude into user-meaningful \emphlogical locations. We describe the design, implementation and our experiences with this system.

Mobile computers often benefit from software which adapts to their
location.  For example, a computer might be backed up when at the
office, or the default printer might always be a nearby one.  In many
existing systems, location-triggered actions are only possible for
specific applications or with special infrastructure.  This paper
describes \emph{lcron}, a system which
supports \emph{user-configurable}
actions triggered on \emph{change in location} or other events common
to mobile computers.  Key features of \emph{lcron} are its use of existing
clues for location information and mapping low-level location
information into user-sensible terms.  \emph{Lcron} uses a number of
existing sources of location such as network connection and base
station ID, allowing it to work without special hardware or GPS
receivers.  We map sources of low-level information such as IP address
and latitude/longitude into user-meaningful \emph{logical} locations.
We describe the design, implementation and our experiences with this
system.
