Decentralized Radio Access Network Virtualization via Distributed Ledger Technology

Abstract

This paper explores the application of distributed ledger technology to facilitate dynamic resource allocation in virtualized radio access networks (RANs). A novel architecture is presented that leverages blockchain to automate the exchange of network functions among diverse stakeholders. This approach addresses challenges related to trust and scalability in open RAN environments, enabling autonomous and secure sharing of infrastructure resources. The proposed system employs auction-based mechanisms and network virtualization to allow entities to transact RAN resources, such as virtual network functions (VNFs), in a decentralized manner. Simulation results demonstrate the potential of this framework to enhance flexibility and efficiency in next-generation mobile networks.
