Vehicular networks allow vehicles to communicate with each other (vehicle-to-vehicle) and with roadside infrastructure (vehicle-to-infrastructure). Vehicles act as moving nodes that form a mobile ad hoc network (MANET). Key aspects include dynamic topology, location-based routing protocols, and applications related to safety, traffic management, and infotainment. Communications can be unicast, multicast, or broadcast between vehicles and infrastructure to support functions like electronic brake lights, platooning, and traffic information systems.

2. Agenda
• What is Vehicular Network.
• Vehicular Network Communication.
• Vehicular Network Architecture.
• Features Of Vehicular Network .
• Protocols Of Vehicular Network.
• Vehicular Network Applications.

3. What is Vehicular Network
• Vehicular Ad Hoc Networks (VANETs)
are created by applying the principles
of MANETs.
• Vehicles Transformed into “Computers
on the Wheels” or “Networks on the
Wheel”.

4. Vehicular Communication

5. Contd...
 Vehicular Communication System (VCS):- Two main
type of communications:
1. Vehicle to Vehicle Communication.
2. Vehicle to Infrastructure Communication.
 Communication between V2V and V2I are “ad-hoc"
in nature.
 This special kind of communication network is
known as
“Vehicular Ad-hoc Network (VANET)”
 VANET will become Worlds largest ad-hoc network

6. Vehicle To Vehicle Communication
High bandwidth link with vehicle and roadside
equipment.
Roadside units broadcast messages.

7. Vehicle to Infrastructure
communication
Uses multi-hop/multi cast technique.
 uses two type of broadcasting
1. naive broadcasting
2. intelligent broadcasting
