随着无线网络技术的发展,电视频谱资源日益稀缺.提出一种认知无线电网络(Cognitive Radio Network,CRN)中基于区块链的电视频谱资源分配方法.主用户(Primary Users,PUs)可以在满足自己通信质量要求的情况下对次用户(Secondary Users,SUs)的干扰功率进行定价来控制SUs的传输,SUs根据自身利益,选择是否付出一定的代价接入PUs的频段,且资源分配方案通过智能合约记录在区块链上.将PUs与SUs之间的相互作用制定为一个斯塔克尔伯格(Stackelberg)博弈问题,利用所采用的算法求解均衡.仿真结果表明了所提方法的有效性.
Blockchain-Based Television Spectrum Resource Allocation Method in Cognitive Radio Network
With the development of wireless networks, television spectrum resources are increasingly scarce. This paper proposes a blockchain-based television spectrum resource allocation method in Cognitive Radio Network (CRN). Specifically, Primary Users (PUs) can set a price on the interference power of Secondary Users (SUs) to control the transmission of SUs under the condition of meeting their own communication quality requirements. SUs choose whether to pay a certain price to access the frequency band of PUs according to their own interests. And the resource allocation scheme is recorded on the blockchain through the smart contract. We formulate the interaction between PUs and SUs as a Stackelberg game problem and solve the equilibrium using the adopted algorithm. Simulation results show the effectiveness of the proposed method.
