A growing class of smartphone applications are
tasking applications that run continuously,
process data from sensors to determine the user's context (such as
location) and activity, and optionally trigger certain actions when
the right conditions occur. Many such tasking applications also involve
coordination between multiple users or devices. Example tasking applications include
location-based reminders, changing the ring-mode of a phone
automatically depending on location, notifying when friends are
nearby, disabling WiFi in favor of cellular data when moving at more than a
certain speed outdoors, automatically tracking and storing movement
tracks when driving, and inferring the number of steps walked each
day. Today, these applications are non-trivial to develop, although they
are often trivial for end users to. Additionally, simple implementations
can consume excessive amounts of energy. This paper proposes
Code in the Air (CITA), a system which simplifies the rapid development of
tasking applications. It enables non-expert end users to easily
express simple tasks on their phone, and more sophisticated developers
to write code for complex tasks by writing purely server-side scripts.
CITA provides a task execution framework to automatically distribute
and coordinate tasks, energy-efficient modules to infer user
activities and compose them, and a push communication service for
mobile devices that overcomes some shortcomings in existing push
services.
