Title: High-Resolution, Low-Power Time Synchronization an Oxymoron No More

Abstract: <p> The time synchronization service has become an integral part of sensor network platforms and a lot of resources have been devoted to make it stable and more precise. While recent work improved the per-hop accuracy for long multi-hop networks, it seems that the overall mean accuracy has not been improving below about 1.5us, and low-power high-accuracy time synchronization at that level has been missing altogether. In this paper, we will present two key technologies, Temperature Compensated Time Synchronization, and Virtual High-resolution Time, that allow a 10x improvement in average power draw for duty-cycles <0.1% at a synchronization accuracy of <1us. </p> <p> <object width="400" height="300"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=10999698&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=10999698&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="400" height="300"></embed></object><p><a href="http://vimeo.com/10999698">High-Resolution, Low-Power Time Synchronization an Oxymoron No More</a> from <a href="http://vimeo.com/tschmid">Thomas Schmid</a> on <a href="http://vimeo.com">Vimeo</a>.</p> </p>
