摘　　要：区块链技术保障数据安全的可靠性受到电力行业关注,然而区块链的高带宽占用问题影响电力通信网的业务传输。为了尽可能缓解区块链技术引入带来的带宽不足问题,文章提出了面向区块链网络的边缘计算任务分配方案,即视边缘服务器之间的带宽竞争问题为一个非合作博弈问题,并提出采用循环迭代的方法完成问题求解。仿真结果表明,在区块信息同步周期来临时该方案依旧有效地提高了业务上传率,并且通信时延性能接近最优。The reliability of blockchain technology to ensure data security has attracted the attention of the power industry.However,the high bandwidth occupation of blockchain affects the service transmission of power communication network.In order to alleviate the problem of insufficient bandwidth caused by the introduction of blockchain technology as much as possible,this paper proposes an edge computing task allocation scheme for blockchain network,that is,the bandwidth competition between edge servers is regarded as a non-cooperative game problem,and a circular iteration method is proposed to solve the problem.The simulation results show that when the block information synchronization cycle comes,the scheme still effectively improves the service upload rate,and the communication delay performance is close to the best.
