A Blockchain-Enabled Framework for Enhancing IoV Performance: From VANET Simulation to Secure Validation

Reliable and trustworthy communication and event message authentication are crucial for maintaining safety and efficiency in Intelligent Transportation Systems (ITS) within vehicular ad hoc networks (VANETs). The prevailing solutions primarily focus on either mobility and network performance or security concerns, such as message authentication, rarely considering both aspects together. This paper introduces a blockchain-integrated platform that addresses this gap by combining traffic-level modeling using SUMO and OMNeT++/Veins with blockchain-based validation through BlockSim.The proposed approach facilitates a methodical assessment of vehicular communication performance metrics, encompassing latency, packet delivery rate (PDR), and throughput, while concurrently analyzing blockchain-level validation attributes. The research employs the notion within a tangible urban setting, namely Cairo's El-Tahrir Square, demonstrating the impact of network dynamics and mobility patterns on validating secure events. The novelty of the proposed work confirms the framework's ability to recognize cross-layer relationships and illustrate its potential as a foundation for safe, decentralized ITS systems.
