TR-Block: A Trustable Content Delivery Approach in VANET Through Blockchain
Abstract
In the emerging and well-rooted field of Vehicular Adhoc-Networks (VANETs), the imperative of secure content exchange via Vehicle-to-Vehicle (V2V) communication for better safety emphasizes the importance of strong communication protocols. Implementing Information-Centric Networking (ICN) in VANETs allows for more efficient resource utilization via name-based content requests and delivery techniques. However, the dynamic and open nature of VANETs creates major security risks, necessitating rigorous defence against malicious attacks. To address these challenges, we introduce a novel trust-aware VANET framework that integrates ICN and Blockchain for content security. Our method uses authenticated vehicle data to ensure content integrity across the network, resulting in effective and efficient security measures. Through precise simulation, our technique exhibits resilience against malicious assaults by improving bandwidth utilization, throughput transactions, network content utilization, and content delivery in the face of hostile scenarios. The experimental results confirm the efficacy and feasibility of our proposed technique, highlighting its potential to improve VANET content security in real-world applications.
