Blockchain Enhanced VANETs for Secure, Resilient, and Efficient Urban Mobility

Abstract

As urban populations grow, cities face increasing challenges in developing transportation systems that are both efficient and secure. Vehicular Ad Hoc Networks (VANETs) provide a promising solution by enabling real-time communication between vehicles and infrastructure, improving road safety and optimizing traffic flow. However, VANETs encounter issues related to data integrity, privacy, and scalability. The integration of blockchain technology offers a secure, decentralized framework for data sharing and identity verification. This chapter introduces a blockchain-enhanced VANET architecture that tackles these challenges by, Proof-of-Work (PoW) consensus for VANETs, enabling vehicles and infrastructure nodes to share computational efforts with the help of collabrative mining. This approach addresses the resource constraints and real-time requirements typical in VANET environments. enhancing security, reducing traffic delays, and improving system resilience, offering a transformative approach to urban mobility.
