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”.

Vehicular Communication

Internet

Internet Gateway

Vehicle

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

Vehicle To Vehicle Communication

High bandwidth link with vehicle and roadside equipment.

Roadside units broadcast messages.

Vehicle to Infrastructure communication

Uses multi-hop/multi cast technique.

uses two type of broadcasting 1. naive broadcasting 2. intelligent broadcasting

Vehicular Network Architecture

Features Of Vehicular Network

• Dynamic topology

• Mobility models

• Infinite energy supply

• Localization functionality

Protocols In Vehicular Network

• Routing Protocols:

-Position-based Routing (Unicast)

-Geocasting Routing (Multicast)

-Broadcast Routing

VoIP Applications

• Electronic brake lights.• Platooning.• Traffic information systems.• Traffic safety• Traffic management services
