Sensor Networks Motes, Smart Spaces, and Beyond

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. Over the last decade or so, networked sensing devices have become embedded all around us. In this article we look at how sensor network research and applications have evolved and how emerging trends could determine where they're headed.
