Blockchain-based wireless spectrum access method and system

Abstract

The invention discloses a block chain-based wireless spectrum access method, comprising: a spectrum sensing node acquires spectrum hole information of a primary user node; a secondary user node completes the first transaction with the spectrum sensing node, and the secondary user node acquires spectrum hole information ; The secondary user node completes the second transaction with the corresponding primary user node according to the spectrum hole information, and obtains the use authority of the corresponding spectrum; wherein, after the first transaction and the second transaction are completed, the transaction information to be confirmed is generated, and the accounting node The transaction information to be confirmed is packaged to generate a block; the PoP algorithm is used to select the accounting node, and the PoP algorithm includes: replacing the random number in the PoW algorithm with the position information and current timestamp information of the node competing for the accounting right. Aiming at many security problems of the current distributed spectrum access management, the present invention proposes to use block chain technology to manage wireless spectrum access, which effectively improves the security of spectrum access.

Description

technical field [0001] The invention relates to the technical field of frequency spectrum sharing. More specifically, the present invention relates to a blockchain-based wireless spectrum access method and system. Background technique [0002] With the continuous innovation of wireless communication technology, wireless network services have experienced rapid growth and expansion in terms of scale, speed, and breadth. Quality assurance of access and communications poses a number of challenges. The traditional radio access network (Radio Access Network) is increasingly difficult to keep up with the huge increase in the number of wireless users and the requirements for real-time connection services. At present, the solution to this kind of problem is to use distributed and crowdsourced multi-layer network coverage services. Although this method greatly reduces the actual network access cost, it also overcomes the vulnerability of centralized spectrum access management method...

[0002] With the continuous innovation of wireless communication technology, wireless network services have experienced rapid growth and expansion in terms of scale, speed, and breadth. Quality assurance of access and communications poses a series of challenges

The traditional radio access network (Radio Access Network) is increasingly difficult to keep up with the huge increase in the number of wireless users and the requirements for real-time connection services

At present, the solution to this kind of problem is to use distributed and crowdsourced multi-layer network coverage services. Although this method greatly reduces the actual network access cost, it also overcomes the vulnerability of centralized spectrum access management methods to malicious nodes. However, the current distributed spectrum access management is still not completely decentralized. There is always a central node to control the overall situation, which makes the security and privacy features of the distributed system unsuitable.
