Multi-Operator Dynamic Spectrum Sharing for Wireless Communications: A Consortium Blockchain Enabled Framework

To enable secure and efficient dynamic spectrum sharing (DSS) with guaranteed revenue quality of service (QoS) in future wireless communications, we present a consortium blockchain based DSS framework, where the regulators supervise whole process DSS, thus each participant can be guaranteed. Each mobile network operator (MNO) on chain adaptively act as provider or requestor their demand, resource allocation is recorded smart contract. The optimal pricing buying strategies are solved multi-leader multi-follower (MLMF) Stackelberg game model, equilibrium proposed algorithm. We then build prototype Hyperledger Fabric blockchain, average latency evaluated. Simulations evaluations validate feasibility show that increase participants, which provides useful insights for real applications.
