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
