Abstract
The principles of MANETs, or mobile ad hoc networks, form the foundation of vehicular ad hoc networks (VANETs). Vanet was first introduced as "Car to Vehicle ad hoc mobile communication and networking" in 2001. In order to build a communication network and transfer data among vehicles, Vanet were invented. Vanet uses a variety of means to establish communication, including vehicle-to-vehicle communication. In this project, both roadside-to-roadside and vehicle-to-roadside communications are employed, and vehicle-to-roadside communication is taken into consideration. A different term for VANETs is Intelligent Transportation Networks. The "Internet of Vehicles" (Vanet) has expanded into a larger system and will ultimately become the internet. There will be a "Internet of autonomous vehicles" in the not too distant future. Wireless networking is used by Vanets for networking and communication; even LTE and 5G may be used by vanets. In this project, a protocol is being developed to provide security for the established connection in Vanet, i.e., to recognise and stop any network intrusions. The NS2 network simulator is used to implement this protocol for testing purposes.
