KEY TOPICS2. What is a VANET ??? Vehicular Ad-Hoc Network shortly VANET.

VANET is a technology that uses moving vehicles as node.

It allows the vehicles to connect with each other through wireless with in 100 to 200 meter distance.

The primary goal of VANET is to provide road safety.

It also provides some value added services. such as

Email Audio/Video sharing etc….

KEY TOPICS5. How it works ???These are the following steps to link VANET with vehicle.

Each vehicle equipped with Wi-Fi/ Wi-Max device. Unique ID and IP address for each vehicle Each node can communicate with any other node Any vehicle can register its identity to a roadway WAP Collective information stored by the WAPs at a dynamic server

database
