Perspectives on Low-Power Wireless

Energy has always been the number one issue in wireless sensor
networks, both because of the resource constraints of sensor nodes and
because of the need for untethered operation. In particular, the
energy footprint of wireless communication has been the object of a
great deal of interest over the past decade. Many applications of
sensor networks require nodes to operate for months or even years
without supervision, thus making it imperative for nodes to employ
low-power radios
and to duty-cycle them. To complicate matters further, low power
radios are notoriously exposed to the vagaries of RF propagation. The
challenge of achieving energy-efficient and reasonably reliable
communication over lossy links has shaped a large body of experimental
research, mostly driven by the popular Berkeley motes. In this talk, I
will illustrate the highlights of a decade of low-power wireless
research, with an emphasis on the key accomplishments in medium access
and routing.
