Abstract
Multiple-operators (multi-OPs) spectrum sharing mechanism can effectively improve the spectrum utilization in fifth-generation (5G) wireless communication networks. The secondary users are introduced to opportunistically access the licensed spectrum of idle operators (OPs). However, the identity privacy and data security issues raise great concerns about the secure spectrum sharing among multi-OPs. To address these challenges, a permissioned blockchain trust framework is proposed for the spectrum sharing in multi-OPs wireless communication networks in this paper. The Multi-OPs Spectrum Sharing (MOSS) smart contract is designed on the constructed permissioned blockchain to implement the spectrum trading among multi-OPs. Without the need of trustless spectrum broker, the MOSS smart contract enforces multi-OPs to share the spectrum truthfully and designs a punishment mechanism to punish malicious OPs. The MOSS smart contract is tested on the Remix integrated development environment (IDE) and the gas costs of MOSS smart contract is estimated. The performance analysis of the proposed permissioned blockchain trust framework demonstrates that the privacy, openness and fairness of the proposed solution are better than traditional spectrum allocation solutions.
Highlights
Wireless spectrum, as a scarce natural resource, is an essential foundation to support wireless communications
In order to test and estimate the cost of Multi-OPs Spectrum Sharing (MOSS) smart contract visually, the designed MOSS smart contract is compiled in the Remix integrated development environment (IDE) and deployed in the Ganache, which is used for the test case
In this paper, a permissioned blockchain trust framework is proposed for the spectrum sharing in multi-OPs wireless communication networks
Summary
As a scarce natural resource, is an essential foundation to support wireless communications. S. Zheng et al.: Smart Contract-Based Spectrum Sharing Transactions for multi-OPs Wireless Communication Networks the spectrum utilization, security issues of interaction among mutual-trustless entities are severe and have not been considered in previous studies. Due to the high block verification delay and low throughput of the public blockchain, the efficient spectrum sharing cannot be achieved in existing blockchain studies To overcome these issues, in this paper, a permissioned blockchain is constructed for the spectrum sharing in multi-OPs wireless communication networks. The Multi-OPs Spectrum Sharing (MOSS) smart contract is designed on the blockchain for spectrum sharing in wireless communication networks. 1) Based on the constructed permissioned blockchain, a decentralized and secure framework is proposed for the spectrum sharing in multi-OPs wireless communication networks.
