The vision for 6G is getting clearer as we move forward. With a transmission rate of Tbps, the 6G wireless network is expected to have the best connection performance. It will support full spectrum, full coverage and all scenario applications. Because there is a significant spectrum shortage, 6G wireless networks will therefore require hundreds of megahertz to tens of gigahertz spectrum resources.
The imbalance between spectrum demand and availability is exacerbated by the current management strategy, which often advocates static allocation and private use. Therefore, the realization of reliable access, on-demand spectrum resource allocation and full process regulation of spectrum utilization necessitates the urgent need for a secure, efficient and sophisticated spectrum resource management architecture.
With the development of blockchain technology, a new approach to developing a distributed multilateral collaborative management architecture is presented. A new approach to 6G spectrum management and security regulation is offered by the blockchain-based distributed multi-level spectrum blockchain, which is crucial for advancing the management of 6G spectrum resources and 6G implementation.
The first iteration of the SpectrumChain distributed multi-level dynamic spectrum management architecture is presented in this paper. Spectrum blockchain architecture, specific technical benefits of blockchain for managing dynamic spectrum, and relevant key enablers are discussed in depth.
Each subchain manages local spectrum sharing, while the main chain manages worldwide spectrum resource trading and regulatory broadcasting services. In the main chain, which may include several Mobile Network Operators, a regulator and SAS servers, Mobile Network Operators can exchange offers and purchases of spectrum resources on demand and publish regulatory information for regulatory, security and fair spectrum sharing.
A local committee consisting of a SAS server and several spectrum controllers creates a subchain where spectrum controllers can lease spectrum resources to meet the spectrum demands of BSs. The SAS server can periodically update the data in the subchain to the main chain. The hierarchical SpectrumChain architecture can produce a consensus-based fault-tolerant decision process at both the global and local levels, unlike the current SAS architecture.
This capacity facilitates DSS processing efficiency as well as guarantees a certain isolation and flexible scalability between various services.
