AODV routing in VANET for message authentication using ECDSA

A Vehicular Ad Hoc Network (VANET) is a part of MANETs that is formed by wireless connections between cars. In VANETs, routing protocols and other routing related techniques must be adaptable to vehicular-specific capabilities and requirements. Along with the routing in VANET, message security is also one of the major concern. Messages are critical and important like a warning message, so that the message must be authenticated which guarantee´s the message integrity. The authentication of these messages is done with the help of an algorithm called Elliptic Curve Digital Signature Algorithm (ECDSA), which provides an efficient message authentication scheme. A combination of AODV, ECDSA and VANET can make the scenario more efficient and perform better in terms of routing and time delay in message delivery.
