Block-VN: A Distributed Blockchain-Based Efficient Communication and Storage System

Internet of vehicles (IoVs) are connected with each other through Internet. In recent years, IoV provides security mechanisms and quick information sharing schemes, etc. The rapid growth of IoV causes various challenges including data storage, intelligent transport system, selfishness of nodes, distrusted nodes and sensor’s data leakage of information. To overcome data storage and delay in services, a decentralized, distributed, secure, transparent and scalable management system is proposed using blockchain technology. Provable data possession (PDP) scheme is used to validate the new data blocks. Message transfer process argon2 (MTP-Argon2) technique is used for data filtration. Using this technique, the raw data are filtered to remove the duplicate and unnecessary data which are obtained from different nodes. Data storage, less delay in service request or response, more sensor’s data sharing and secure communication channel are achieved using proposed system.
