摘要: 針對地面業(yè)務(wù)的需求和分布非均勻?qū)е孪到y(tǒng)資源利用率低的問題,提出一種基于區(qū)塊鏈的跨低軌衛(wèi)星互聯(lián)網(wǎng)域數(shù)據(jù)共享方案。通過衛(wèi)星節(jié)點構(gòu)建區(qū)塊鏈,實現(xiàn)數(shù)據(jù)的跨域調(diào)度;通過非均勻分布的接入設(shè)備數(shù)量改變礦工節(jié)點的出塊難度,使得近期出塊節(jié)點暫停參與礦工節(jié)點的選舉過程,以降低重復(fù)的資源消耗。仿真結(jié)果表明,所提方案能夠有效降低系統(tǒng)資源消耗和任務(wù)的平均卸載時延,在低軌衛(wèi)星互聯(lián)網(wǎng)中實現(xiàn)高效的跨域數(shù)據(jù)調(diào)度。

Abstract: 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.
Key words : low earth orbit (LEO) satellite Internet; blockchain; data sharing; cross domain
