Both V2V and V2I
works by using
wireless signals to
send information
back and forth
between cars about
their location, speed
and direction over
Vehicular Ad hoc
NETworks
(VANETs) to
prevent accidents.
VANET is the
spontaneous creation of a
wireless network for data
exchange - to the domain of
vehicles. Vehicular Ad Hoc
Networks (VANETs) are
created by applying the
principles of mobile ad hoc
networks (MANETs).
Basically, both VANETs and
MANETs are
characterized by the
movement and selforganization
of the
nodes (i.e., vehicles
in case of VANETs
and mobiles in case
of MANETS).
VANETs are
characterized by
rapid but somewhat
predictable topology
changes, with
frequent fragmentation, a
small effective network
diameter, and redundancy hat
is limited temporally and
functionally.
These
Vehicular
communications is usually
developed as a part
of intelligent transportation
systems (ITS).These
technologies could transform
the way we drive and increase
automotive
safety
dramatically. Good thing is
car companies and the
government are already
working to try to make this a
reality. All of this
communication and
preemptive vehicle assistance
leads us into our next future
technology.
Even
automotive
manufacturers are also
working on Vehicle-toeverything
(V2X). It is
a vehicular communication
system that incorporates other
more specific types of
communication as V2I
(Vehicle-to-Infrastructure),
V2V (Vehicle-to-vehicle),
V2P (Vehicle-to-Pedestrian),
V2D (Vehicle-to-device) and
V2G (Vehicle-to-grid). V2X
is the platform that regulates
all connections a car makes
with the outside world, be that
another car, an IoT device or
even a human
