基于卫星协作的空间信息传输及路由机制研究

In recent years, as significant components of future space-ground-integrated communication, the space transmission and routing technologies have attracted wide attention from many research institutions all over the world. Since the satellite communication networks have features of complex network structure, changeable topology, and instable transmission quality, leading to long transmission delay, high bit error rate, and poor connectivity, etc., Aiming at the transmission self-adaption, the route self-optimization, and network self-organization, this project will research the the space information transmission and routing mechanisms based on the satellite cooperation. By exploiting the methods of space cooperative transmission, dynamic time-space connection, and joint cross-layer optimization, we establish the space information transmission model. With which, we focus on solving the key problems on optimization of space resource, stabilization of information transmission, joint routing of multilayer, etc., and propose the space information cooperative transmission and routing schemes. The conduct of this project can significantly contribute to our future space-ground-integrated communication strategy on both theoretical and technical aspects.

近年来，空间信息传输及路由技术作为未来空天地一体化通信的重要组成部分，已受到各国研究机构的广泛关注。由于卫星通信网络结构复杂、拓扑动态、传输质量不稳定，容易造成传输时延长、误码率高、连通性差等问题，本项目将以“传输自适应、路由自优化、网络自组织”为目标，研究基于卫星协作的空间信息传输及路由机制。通过引入空间协作传输、动态时空连接、跨层联合优化等方法，研究建立空间信息传输模型，解决空间资源优化、信息稳定传输、多层联合路由等关键问题，设计提出空间信息协作传输及路由方案。该项目的研究将为实现我国未来空天地一体化的通信战略提供必要的理论基础和技术支持。
