Abstract
With the proliferation of mobile wireless devices such as
smartphones and tablets that are used in a wide range of
locations and movement conditions, it has become important
for wireless protocols to adapt to different settings
over short periods of time. Network protocols that
perform well in static settings where channel conditions
are relatively stable tend to perform poorly in mobile
settings where channel conditions change rapidly, and
vice versa. To adapt to the conditions under which communication
is occurring, we propose the use of external
sensor hints to augment network protocols. Commodity
smartphones and tablet devices come equipped
with a variety of sensors, including GPS, accelerometers,
magnetic compasses, and gyroscopes, which can provide
hints about the device’s mobility state and its operating
environment.We present a wireless protocol architecture
that integrates sensor hints in adaptation algorithms. We
validate the idea and architecture by implementing and
evaluating sensor-augmented wireless protocols for bit
rate adaptation, access point association, neighbor maintenance
in mobile mesh networks, and path selection in
vehicular networks.
