Abstract (EN):
In this paper, we evaluate the performance of
802.11p-based vehicular communications in the presence of radio
frequency (RF) jamming attacks. Specifically, we characterize the
transmission success rate of a car-to-car link subject to constant,
periodic, and reactive RF jamming. First, we conduct extensive
measurements in an anechoic chamber, where we study the benefits
of built-in techniques for interference mitigation. In addition,
we identify that the periodic transmission of preamble-like jamming
signals can hinder successful communication despite being
up to five orders of magnitude weaker than the signal of interest.
We further provide the rationale behind this remarkably high
jamming effectiveness. Additionally, we quantify the impact of
reaction delay and interference signal length on the effectiveness
of the reactive jammer. Then, by means of outdoor measurements,
we evaluate the suitability of using the indoor measurements as a
model to characterize the performance of car-to-car communications
in the presence of RF jamming. Finally, we conduct outdoor
measurements emulating a vehicular platoon and study the threats
that RF jamming poses to this vehicular ad hoc network (VANET)
application. We observe that constant, periodic, but also reactive
jamming can hinder communication over large propagation areas,
which would threaten road safety.
