摘　　要：针对地面业务的需求和分布非均匀导致系统资源利用率低的问题,提出一种基于区块链的跨低轨卫星互联网域数据共享方案。通过卫星节点构建区块链,实现数据的跨域调度;通过非均匀分布的接入设备数量改变矿工节点的出块难度,使得近期出块节点暂停参与矿工节点的选举过程,以降低重复的资源消耗。仿真结果表明,所提方案能够有效降低系统资源消耗和任务的平均卸载时延,在低轨卫星互联网中实现高效的跨域数据调度。In order to reduce the problem of low utilization rate of system resources,which is caused by the uneven of the demand and distribution of ground services,a cross-domain data sharing scheme based on block chain is proposed in the low earth orbit satellite Internet.By building block chain through satellite nodes,distributed storage of shared data is realized.The non-uniform distribution of the number of access devices changes the difficulty of miner node block production,so that the recent block production node is suspended from participating in the election process of miner node,so as to reduce repeated resource consumption.Simulation results show that the proposed scheme can effectively reduce the system resource consumption and the average unloading delay of tasks,and realize efficient cross-domain data scheduling in the low-orbit satellite Internet.
