星际互联网作为深空通信网络化发展方向的重要研究成果，能够为各类深空探测任务提供通信、导航和测控服务。然而，由于拓扑结构的动态变化以及网络内各局部之间产生的耦合，造成全网状态的高动态变化，使得采用统一的网络管理与控制非常困难。本课题立足深空探测基本需求，结合星际互联网发展趋势，研究各空间节点、天体等要素的动态相对关系，分析深空通信链路的通断演变规律，构建星际互联网体系架构，根据节点属性、功能、区域位置及任务需求，将网络中节点划分为不同簇，建立分簇组网模型，提高网络管理控制效率；在分簇组网基础上建立簇间、簇内网络路由控制与选择算法，简化网络的管理控制与路由计算工作；通过资源自主优化利用、链路高效协作传输、基于信道认知的差错控制等理论建立端到端可靠传输机制。为我国未来星际互联网发展提供基础理论、技术支持和具有前瞻性的探索。

As one of the most important research results for deep space communication networking, Interplanetary Internet can provide different kinds of services, including communication, navigation and TT&C for deep space exploration missions. However, due to the dynamics of the topological structure and the coupling caused by different parts, the network level highly dynamic changes will be caused,which makes it difficult to use unified network management and control of the entire network. This project will study the relative dynamic relationships of every space node and celestial elements with the development trend of Interplanetary Internet and some other factors, the evolution of the deep space communication link will be analyzed, The system architecture of Interplanetary Internet will be built, the cluster-oriented model will be designed according to the node properties, functions, regional distributions and mission requirements et al, which can improve the efficiency of network management. The routing control and selection algorithms for inter-cluster and intra-cluster will be studied based on the cluster-oriented model, which can simplify the management control and routing calculations. Finally, we will study the reliable end-to-end transport mechanism through independent utilization of resources, efficient collaboration transmission and the error control theory based on the channel cognition et al. In a word, we will provide the theoretical basis, technical support and perspective exploration for the development of our future Interplanetary Internet through this project.
