Abstract: Connected vehicles communicate either with each other or
with the fixed infrastructure using Dedicated Short Range Communication
(DSRC). The communication is used by DSRC safety applications, such as
forward collision warning, which are intended to reduce accidents. Since
these safety applications operate in a critical infrastructure, reliability
of the applications is essential. This research considers jamming as the
source of a malicious act that could significantly affect
reliability. Previous research has discussed jamming detection and
prevention in the context of wireless networks in general, but little focus
has been on Vehicular Ad Hoc Networks (VANET), which have unique
characteristics. Other research discussed jamming detection in VANET,
however it is not aligned with current DSRC standards. We propose a new
jamming-aware algorithm for DSRC safety application design for VANET that
increases reliability using jamming detection and consequent fail-safe
behavior, without any alteration of existing protocols and standards. The
impact of deceptive jamming on data rates and the impact of the jammer’s
data rate were studied using actual field measurements. Finally, we show the
operation of the jamming-aware algorithm using field data.
