Trust-based Blockchain Mechanism for V2X Networks in a Smart Grid Environment

The role of Vehicle-to-Everything (V2X) networks in smart grid applications has become increasingly important in recent years, largely due to integrating electric vehicles (EVs) with the grid, such as charging stations, other EVs, smart homes, and grid control centers. However, the decentralized and complex nature of V2X networks raises security concerns. Previous research suggests using blockchain technology to mitigate these concerns. Therefore, we examine a V2X network scenario employing a Trust-based Access control Blockchain mechanism for IoT networks (TABI). This mechanism, when applied to V2X networks, is referred to as the Trust-based Blockchain mechanism for V2X networks (TBVX) mechanism. We use the Hyperledger Fabric (HLF) blockchain network and Hyperledger Composer to analyze the V2X network scenario. Also, we use the Hyperledger caliper to evaluate the performance of TBVX in terms of throughput and latency. Our experimental analysis shows the effectiveness of the TBVX mechanism in the V2X network scenario.
