Blockchain-Enabled Secure Communication for Autonomous Vehicles

This research study introduces an innovative Vehicle-to-Everything (V2X) communication system utilizing Ethereum blockchain and Solidity smart contracts. The proposed approach transcends conventional vehicular communication systems by integrating the inherent security and transparency of blockchain technology. This integration aims to revolutionize V2X interactions, encompassing vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, ensuring enhanced security, reliability, and immutability of data exchanged in urban traffic environments. The foundation of our system is a strong Solidity smart contract deployed on the Ethereum blockchain. This contract orchestrates the V2X communication, providing a decentralized and tamper-proof platform for transmitting and receiving data across various urban traffic entities. The practical application of this system is demonstrated through simulations in an urban environment created in Netedit, with various traffic scenarios evaluated using the Simulation of Urban Mobility (SUMO) software.
