Analysis Of Unicast Routing
Protocols For VANETs
1
Introduction


Nowadays, most cars include
Global Positioning System (GPS)
devices, so the position of each
vehicle can be determined at realtime.

as soon as two or more vehicles
are close enough to establish a
communication level.
Introduction


The routing protocols can be
classified as follows:

According to range: anycast, unicast,
broadcast, multicast;

According to the route discovery:
proactive, reactive, hybrid;

According to the used algorithm: link
state, vector distance, georouting.

Simulation of car-to-car
communications

In the first case, a simulation
among 10 nodes is done. This
communication takes place
between the first and the last
vehicle with 8 vehicles between
them.
