Abstract

Fog-enabled Internet of Things (IoT-Fog) architectures and the Cognitive Internet of Vehicles (Cognitive IOV) are becoming key enablers for next-generation intelligent transport systems. At the same time, Blockchain is used to support integrity, transparency, and trust in distributed vehicular services. In this perspective article, we link these domains by discussing a hybrid Mutable-Immutable Blockchain Architecture in which mutable ledgers at the fog layer are combined with an immutable ledger in the cloud. We first outline an analytical model for Cognitive IOV over IoT-Fog, and then extend it to include Blockchain-related delays, throughput, and tamper resistance in the hybrid architecture. The main contribution is an analytical view of how key parameters, such as the fraction of transactions sent to the Blockchain or anchored in the immutable layer, influence the trade-off between latency, flexibility, and security in Cognitive IOV services.
