Routing finds the best optimal routing among a source and destination pair of vehicles. Secure routing is the main issue in VANETs owing to the dubious wireless medium and highly frequent link disconnections. The attackers alter the VANET safety messages and lead the drivers to take wrong decisions, resulting in degradation in network performance. The secure VANET routing protocols integrate cryptography schemes, IDS schemes, and intelligent algorithm-based solutions to avoid the impact of attacks in the VANET system.
