Title:
MARVEL: Multiple Antenna based Relative Vehicle Localizer

Abstract:
Access to relative location of nearby vehicles on the local roads
or on the freeways is useful for providing critical alerts to the
drivers, thereby enhancing their driving experience as well as
reducing the chances of accidents. The problem of determining the
relative location of two vehicles can be broken into two smaller
subproblems: (i) Relative lane localization, where a vehicle
determines if the other vehicle is in left lane, same lane or right
lane with respect to it, and (ii) Relative front-rear localization
where it needs to be determined which of the two vehicles is ahead
of the other on the road. In this paper, we propose a novel antenna
diversity based solution, MARVEL, that solves the two problems of
determining the relative location of two vehicles. MARVEL has two
components: (i) a smartphone; and (ii) four wireless radios. Unlike
exisiting technologies, MARVEL can also determine relative location
of vehicles that are not in the immediate neighborhood, thereby providing
the driver with more time to react. Further, due to minimal hardware
requirements, the deployment cost of MARVEL is low and it can be
easily installed on newer as well as existing vehicles. Using results
from our real driving tests, we show that MARVEL is able to determine
the relative lane location of two vehicles with 96.8% accuracy. Through
trace-driven simulations, we also show that by aggregating information
across different vehicles, MARVEL is able to increase the localization
accuracy to 98%. I will also talk about some other problems related to
vehicular communications and networking that we are currently working on.
