 INTRODUCTION
 DESCRIPTION OF AD HOC ROUTING PROTOCOLS
 SIMULATION OF CAR-TO-CAR
COMMUNICATIONS
 RESULTS

 Nowadays,most cars include Global Positioning
System(GPS) devices, so the position of each vehicle
can be determined at real-time.
 As soon as two or more vehicles are close enough to
establish a communication level.
3
 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.
4
 Dynamic Source Routing (DSR)

 Ad Hoc On-Demand Distance Vector(AODV)

 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.

 The final objective will be the creation of a specific
routing protocol based on geographical coordinates for
VANET networks.
