Efficiency and Reliability of Avalanche Consensus Protocol in Vehicular Communication Networks

An vehicular communication networks, security issues such as privacy preservation, secure authentication, and threats from insiders and compromised authorities pose significant challenges due to the centralized nature of existing systems. Addressing these concerns, we propose a blockchain based system that decentralizes control and enhances security using the Avalanche consensus protocol, known for its innovation and scalability. Our proposed system achieves a substantial throughput, with PBFT registering 12.8 transactions per second (TPS) and Avalanche demonstrating an impressive 1007 TPS for 100 validators. In terms of delay, PBFT experiences 6.61 seconds, whereas Avalanche achieves a remarkably low delay of just 1 millisecond, both with 100 validators. These findings underscore the superiority of our proposed system, offering heightened security, privacy, and transaction throughput essential for future vehicular communication systems.
