Blockchain and Game Theory Convergence for Network Slice Brokering

As a distributed ledger technology, blockchain has received significant attention in revolutionizing telecommunication and networking domains. This article proposes a blockchain-based network slice brokering mechanism for multioperator and multitenant environments of the envisioned 6G networks.

The 6G telecommunication infrastructure is expected to facilitate more diversified consumer requirements arising from various emerging use cases. The 5G network slicing allows on-demand creation of multiple end-to-end (E2E) logical networks over a common physical (mobile network) infrastructure. Following the trends observed in the 5G era, 6G is envisioned to intensively use sophisticated and secure slicing for complex multitenant multioperator scenarios.
