What is VANET? I
Vehicles Transformed into “Computers on the Wheels” or“Networks on the Wheel”
Vehicular Communication System (VCS):- Two main type ofcommunications
Vehicle to Vehicle (V2V) Communication:-Vehicle to Infrastructure (V2I) communication:-
Advantage and Usage of VCS:-
Information sharingCo-operative drivingOther value added services like Navigation, internet access etc.
Communication between C2C adn C2I are “ad-hoc” in nature.
This special kind of communication network is known as“Vehicular Ad-hoc Network (VANET)”

Communication:- Wireless Access in Vehicular Environment(WAVE): IEEE 1609.2 Standard also Known DSRC 802.11p .
Supports Multi-Hop communication for vehicles out of range(Max. Range DSRC is 1000m)
On-Board Unit (OBU):- A device which is inside the vehiclewhich -
processes the data collected from various sensors fitted insidethe cars and gives conditions of the vehiclesis responsible for communication with outside network i.e withother vehicles and infrastructure.
Road Side Unit (RSU): Infrastructure for communicationbetween the cars for sharing and information from variousvehicles.

Possible Threat in Scenarios of V2I above:-Electronic Toll collection/Automatic access control/parkingaccess:- Privacy Violation, Impersonation,
Infotainment:- Penetration attack, Privacy violation
Remote Fleet Management:- Tracking/Profiling
Tax payment: The authority can link or indentify usingprevious transaction or other vehicle can hack transactioninformation and reveal the identity of the sender.
