5G Resource Sharing Scheme and Consensus Algorithm Based on Blockchain.

One of the outstanding features of 5G is the powerful resource sharing ability to cope with the increasing content demand and data usage, especially in 5G IoT scenarios. However, due to data attacks, sharing resources in mobile networks is extremely vulnerable to serious data leakage risks and security threats. Blockchain has the characteristics of decentralization, security, non-tamperability, and incentive mechanism, which enables this emerging disruptive technology to provide innovative solutions to the challenges in 5G networks. This paper combines resource sharing in 5G with blockchain technology, proposes a blockchain-based 5G resource sharing architecture, provides incentives for resource sharing between nodes, and considers the latency issue in 5G, and proposes BFT-PoS consensus algorithm, which combined PBFT and PoS, improves the efficiency of the consensus algorithm and is verified by simulation.
