However, due to poor communication environment in deep space communications, aerospace and information network, disaster relief network environment, the link frequent interruption leading to end-to-end path does not necessarily exist, and the traditional routing protocols cannot work effectively. 但在深空通信、空天信息网络、灾难救援等网络环境下,由于通信环境恶劣,链路频繁中断导致端到端路径不一定存在,传统路由协议无法有效运行。
A simulation platform specially designed for routing algorithms on the simulator OPNET Modeler is completed according to the deep space network characteristics and available technologies. 然后我们根据深空骨干网的特点和现有技术在OPNETModeler上搭建了一个仿真平台,并在此平台上主要研究骨干网的路由协议。
In this paper, infrastructures and protocol stack of deep space network are firstly introduced with the applicability of traditional protocols analyzed subsequently. 本文首先系统地介绍了深空骨干网的网络结构以及协议栈,并分析了现有的协议在深空网络的适用性。
The deep space backbone network has the distinctive characteristics such as very long propagation delay, link asymmetry and intermittent connectivity, hence routing through the backbone network present many challenges that are not presented in traditional networks. 深空骨干网由于具有长时延、非对称性链路、不连续的链路等独有的特点造成了深空网络研究的复杂性。
The designed scheme has established a solid foundation for the future application of deep space detection, inter-satellite high speed data link, satellite formation and astro network. 该方案为将来的深空探测、星-星高速数据链路、卫星编队和星座组网应用奠定了基础。为进一步验证和优化该系统设计方案,对太赫兹空间通信链路进行了数值仿真。
It is possible to be in despair even if using maximum antenna apertures and lower receiver noise temperatures such as in Deep Space Network and military communication. 例如深空通信和军事通信中,即使采用最大口径天线和最低噪声温度接收机也可能难以实现信号的有效接收。
The network architecture which arises in various contexts, such as vehicle network, wildlife monitoring, deep space exploration, rural communication and military battlefield network, is very valuable for both theoretical research and practicability. 这种网络体系结构在车载网络,野生动物追踪,深空探测,乡村通信和军事战场网络等多种网络上有着很强的理论研究和实用价值。
