THIS INSTALLMENT OF Research for Practice features
a curated selection from Deepak Vasisht, who takes
us on a tour of systems and networking for the
Internet of Things. Vasisht’s selection spans energy
harvesting to agriculture, providing a look into the
future of Io T deployments and their usability.
Peter Bailis is an assistant professor of computer science at Stanford University.
His research in the Future Data Systems group ( futuredata.stanford.edu) focuses
on the design and implementation of next-generation data-intensive systems.
Over the past few years, we
have started realizing the
Internet of Things (IoT)
dream. Amazon Echo,
Dash buttons, Nest cameras, Google Home, and
other devices have permeated our lives
at home, and enterprises in various sectors such as retail, airlines, transportation, and logistics have started benefiting from industrial IoT solutions.
Inspired by this impetus, General Electric recently estimated that investments
in industrial Io T alone would top $60
trillion over the next 15 years.
All this growth has been fueled
by years of research tackling several
challenges, ranging from low-power
networking to new sensor designs to
security and privacy. This installment
of Research for Practice presents research papers that aim to make IoT
deployments more pervasive, and to
enable users to gain more utility from

HitchHike: Practical backscatter using
commodity Wi-Fi. In Proceedings of the 14th
ACM Conference on Embedded Network Sensor
Systems CD-ROM, 2016, 259–271; https://dl.
One of the natural challenges of large-
scale networked sensor deployments
is the cost of powering them up. The
high power cost of communication
modules leads to frequent battery re-
placements, which, in turn, incur large
labor costs. A recent sequence of back-
scatter solutions aims to change that
by leveraging existing radio frequency
transmissions to communicate. Spe-
cifically, backscatter communication
systems allow devices to modulate and
reflect existing Wi-Fi transmissions,
thus enabling low-power communica-
tion modules that could be powered
either by harvesting ambient power or
by batteries that last several years.
HitchHike is unique for two reasons.
First, not only can it reflect transmis-
sions from commodity Wi-Fi devices,
its reflections can also be received and
