A Novel Blockchain-Based Fault-Tolerant Authentication Technique for Secure and QoS Aware Vehicular Ad Hoc Network Using

Abstract

A software-defined vehicular network combines the benefits of IoV-based vehicular ad-hoc networks with software-defined networks to improve overall system performance, reliability, and security. We proposed software defined Fault Tolerance Authentication and QoS – aware IoV framework for communication among smart vehicular network using Edge computing secured by Blockchain to reduce overall communication delay ,message failure Fault Tolerance and  secure service provisioning for VANET. The proposed model aims to improve the performance and reliability of vehicular ad-hoc networks by incorporating edge computing and blockchain technology. The use of edge servers placed on the roadside reduces communication delays by processing messages locally instead of relying on cloud computing. The SDN controller in the edge server categorizes messages based on priority, size, and emergency situation and forwards them to their destination. The fault tolerance mechanism checks for message delivery failures and resends the message if needed. The use of blockchain technology validates and verifies the edge server, providing secure services to the vehicles on the road. The proposed model is evaluated using NS2 simulator and shows a reduction in overall message communication delay and overhead performance improved the throughput packet delivery ratio.
