Decentralized Vehicle to Infrastructure Communication and Data Exchange Using Proof of Stake

Abstract

A growing requirement for intelligent transportation systems (ITS) and vehicle-to-infrastructure (V2I) communication provides the foundation for a safe, highly-scalable, and decentralized tolling and real-time data exchange solution. Blockchain solutions typically incorporate the overhead burden of using consensus algorithms such as PBFT, which do not provide the scalability required in dynamic vehicular environments. This thesis proposes a decentralized V2I communication and data exchange mechanism, based on using a Proof of Stake (PoS) Blockchain. Smart contracts facilitate toll collection, transaction confirmation, and record keeping for V2I vehicle communication via an unbiased blockchain ledger that is immutable. Therefore, the proposed framework creates transparency, tamper-resistance, and data security for the exchange of V2I communication. This work achieves an improvement in communication infrastructurerelated latency and scalability, allowing for applications in many different real-time V2I cases by substituting the communicationintensive nature of POS for the consensus-based approach of existing blockchain systems.
