Blockchain-Enabled Dynamic Spectrum Sharing for Massive MIMO-NOMA in 6G Networks

With the nature of decentralization, blockchain in spectrum sensing allows users to rent or lease spectrum without any centralized authority. This project proposes a blockchain-enabled dynamic spectrum-sharing framework integrated with Massive MIMO and NOMA to address spectrum scarcity in 6G networks. Blockchain's decentralization ensures secure and transparent spectrum allocation, while Massive MIMO enhances capacity and reliability, and NOMA facilitates efficient user coexistence. Simulation results demonstrate significant improvements in spectrum utilization, reduced interference, and compliance with 6G requirements. Smart contracts in blockchain automate the spectrum allocation and ensure the fair use of compliance without manual intervention. The integration of Massive MIMO increases signal reliability and capacity, while NOMA facilitates efficient spectrum sharing among multiple users. Also, this project provides a solution for dynamic spectrum management that addresses both the technical and security challenges in future-generation wireless communications.
