A cross domain data scheduling scheme based on blockchain for low orbit satellite Internet

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.
