of social structure that I call the network society for reasons that hopefully will become apparent. I shall summarize below the main features of these transformations, in a sequential order that does not imply hierarchy of causation in any way. We have entered a new technological paradigm, centred around

we thought a bit faster than we spoke) and were in phase. And that's still the way things stand now, speaking, for, after the advent of language, the rest of the developments in the linguistic arena were (and cultural) rather than biological --feats of "cognitive engineering," if you

As wireless sensor networks continue to grow in size, we are faced with the prospect of emerging wireless networks with hundreds or thousands of nodes. Geographic routing algorithms are a promising alternative to tradition ad hoc routing algorithms in this new domain for point-to-point routing

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

This thesis presents CraneTracker, a multi-modal sensing and communication system for monitoring migratory species at the continental level. By exploiting the robust and extensive cellular infrastructure across the continent, traditional mobile wireless sensor networks can be extended to enable

Abstract: Mobile ad hoc networks (MANETs) and wireless sensor networks (WSNs) are two recently-developed technologies that uniquely function without xed infrastructure support, and sense at scales, resolutions, and durations previously not possible. While both offer great potential in many
