展示并验证了一种由新一代低轨卫星网络和地面无线自组织网络组成的星地一体化网络。此星地一体化网络中的低轨卫星网络可以提供大容量、低时延的网络覆盖,其“低轨”的特点又可减小地面终端的尺寸,增强地面网络的移动性。与经典的中轨和静止卫星网络相比,此种网络可以提供更高通量、更高移动性的通信支持,大大拓宽通信网络的应用范围。对不同的网络层次结构采用相应的软件仿真工具环境,为今后进一步深入研究卫星网络的体系结构和自组互联网技术起到了抛砖引玉的作用。
Demonstrated and verified a satellite-to-ground integrated network comprised of a new generation of LEO satellite networks and terrestrial wireless ad hoc networks. The low earth orbit satellite network in this satellite integrated network can provide high capacity and low latency network coverage. Its “low rail” feature can reduce the size of the ground terminal and enhance the mobility of the terrestrial network. Compared with the classic medium-orbit and geostationary satellite networks, such networks can provide higher-throughput and higher-mobility communication support, greatly expanding the application range of communication networks. The corresponding software simulation tool environment is adopted for different network hierarchies, which paves the way for further research on the architecture of satellite networks and self-organizing Internet technologies in the future.
