Sensor Networks: Motes, Smart Spaces, and Beyond
Raja Bose, IEEE Pervasive Computing

"Sensor networks have come a long way since their humble beginnings in
DARPA-funded academic research projects in the 1990s and have morphed
into a significant research area in their own right. In this article we
look at how sensor network research and applications have evolved and
how emerging trends could determine where they're headed.

The goal of early research was to design and create tiny autonomous
computers (called sensor platforms or in some cases motes) that could
unobtrusively observe their environment through built-in sensors and
report back to a remote base station. The primary use cases involved
scattering hundreds or thousands of these sensor platforms in an area
and tasking them with monitoring vehicular movement or environmental
conditions and periodically reporting the data...

The Atlas Platform, developed at the Mobile and Pervasive Computing
Laboratory of the University of Florida, was one of the first sensor
platforms to utilize Service-Oriented Architecture (SOA) for automatic
self-integration of sensors and actuators into smart spaces... the SOA
paradigm in conjunction with the use of IP-based networking allows
Atlas to easily integrate sensors and actuators into existing business
process management and IT systems.

Another application domain where mobile phone based sensing is gaining
increasing acceptance is environmental sensing, in particular pollution
tracking...Mobile phones equipped with air pollution sensors and GPS
are used as data-collection points for sensing and mapping pollution
levels in their users' local surroundings. Data from multiple phones
are fused and processed to provide a comprehensive picture of pollution
in various parts of the city, at various times. Researchers can link
this data with health statistics and other parameters to determine
pollution effects on the local weather, incidence of airborne diseases
and living conditions in specific neighborhoods..."
