Internet of Planets (IoP) is a concept that enables solar planets to communicate with each other using the Internet. While there is a plethora of research on IoP, the delay-tolerant network (DTN) has emerged as the most advanced technology in recent years. DTN is an asynchronous networking technology that has been deployed for the networking environment in which steady communication paths are not available, and therefore, it stores receiving data in a data storage and forward them only when the communication links are established. DTN can be applied to sensor networks and the mobile ad-hoc network, as well as space communication that supports data transmissions among satellites. In DTN networking environments, it is crucial to secure a scheme that has relatively low routing overhead and high reliability to achieve efficiency. Thus, this article proposes a time (delay) information based DTN routing scheme, which is able to predict routing paths for achieving efficient data transmissions among the nodes that have comparatively periodic moving patterns. The results of the proposed DTN routing algorithm using NS-3 simulation tools indicate satisfied levels of routing performance in comparison with the existing DTN algorithm.

行星互联网 (IoP)：互联网的新时代


行星互联网（IoP）是一个使太阳行星能够通过互联网相互通信的概念。虽然 IoP 方面的研究非常多，但延迟容忍网络 (DTN) 已成为近年来最先进的技术。 DTN是一种异步组网技术，针对没有稳定通信路径的组网环境而部署，因此它将接收的数据存储在数据存储器中，只有在建立通信链路时才转发它们。 DTN可应用于传感器网络和移动自组织网络，以及支持卫星间数据传输的空间通信。在DTN网络环境中，确保具有相对较低的路由开销和高可靠性的方案对于实现效率至关重要。因此，本文提出了一种基于时间（延迟）信息的DTN路由方案，该方案能够预测路由路径，从而在具有相对周期性移动模式的节点之间实现高效的数据传输。使用 NS-3 仿真工具所提出的 DTN 路由算法的结果表明，与现有的 DTN 算法相比，路由性能达到了令人满意的水平。
