TokenNet: A Novel Tokenized Resource Marketplace for 6G Network Slicing

Abstract

The transition from fifth-generation (5 G) to sixth-generation (6 G) networks is driving significant advancements in network slicing, fueled by the growing demand for next-generation applications and services. However, managing these advancements within the constraints of finite resources creates the opportunity for open resource marketplaces, which introduces technical and business challenges. To address these, we propose TokenNet, the first blockchain-based architecture that represents network resources as non-fungible tokens (NFTs) in the context of network slicing. TokenNet facilitates secure, decentralized resource trading, ownership traceability, and management, optimizing resource allocation through auctioning, brokering, and trust mechanisms. It offers more granular, flexible, and trustworthy control over network resources compared to existing state-of-the-art systems. Our prototype implementation demonstrates its effectiveness, outperforming baseline models in cost efficiency, reducing delays, and improving minting performance. These advantages position TokenNet as a promising solution for future network management.
