摘要
分析了主要应用于大型星座等空间拓扑稳定的可预测组网技术,以及应用于空间Ad hoc、Mesh等网络需要灵活组网的空间自组织组网技术。针对空间自组织组网技术,对具备抗高丢包适应多跳网络的分批稀疏编码进行空间自组网的应用分析。仿真结果表明:在高丢包的自组织空间网络中,应用分批稀疏编码后系统吞吐量得到明显提升。可预测网络的主要发展趋势是超大规模星座组网技术与精密编队组网控制一体化技术,自组织网络主要趋势为低开销高性能及自适应性。
The predictable networking technologies are analyzed,which is mainly used in stable space system such as large constellations,and the space self-organizing networking technologies which meets flexible networking,such as space Ad hoc,Mesh networks.Aiming at the space self-organizing networking technologies,the application of spatial self-networking for BATS(batch sparse)coding with anti-high packet loss in multi-hop network is analyzed,and the simulation results show that in self-organizing space networks with high packet loss,the throughput of the system is obviously improved after the batch sparse coding is applied.The main development trend of predictable network is super-large constellation networking technology and the integrated of network and control technology for precision formation,and the main trend of self-organizing network is low cost,high performance and self-adaptability.
