摘要

考虑到科学和经济机会，一些公共和私人组织将在月球上建立殖民地。特别是，月球殖民可以是深空任务的第一步，初始阶段是通过部署许多物联网设备和系统来完成的。因此，必须设计由地球卫星和月球卫星段结合而成的专用地月主干网。考虑到它的元素本身是可移动的，为了确保连接，应该对组成设备进行编程，使其在特定的时间间隔内正常运行。软件定义网络（SDN）范例的特性允许实现这一目标。此外，时序网络（Temporal Networks, TNs）的理论框架为优化转发规则提供了可能。根据这些原则，本文提出了一种基于sdn的架构，并分析了整体通信场景，提出了优化数据速率的具体策略。性能评估考虑了端到端（E2E）最佳路径持续时间、跳数、控制数据包延迟、功率预算和容量。结果表明，在有限的开销下，建立按需组网策略以支持连续物联网数据流的传输是可行的。

From Earth-to-Moon Networking: A Software-Defined Temporal Perspective

Considering the scientific and economic opportunities, several public and private organizations are going to establish colonies on the Moon. In particular, lunar colonization can be a first step for deep space missions, and the initial phase is accomplished with the deployment of many Internet of Things (IoT) devices and systems. Therefore, a dedicated Earth-Moon backbone, which results from the combination of terrestrial and lunar satellite segments, must be designed. Considering that its elements are inherently mobile, to ensure the connection, the constituent devices are supposed to be programmed to properly operate during specific time intervals. The features of the Software-Defined Networking (SDN) paradigm allows achieving this aim. Moreover, the Temporal Networks (TNs) theoretical framework makes it possible to optimize the forwarding rules. In light of these principles, this paper proposes an SDN-based architecture and analyzes the overall communications scenario proposing a specific strategy to optimize the data rate. The performance was evaluated considering the End-to-End (E2E) best path duration, the number of hops, the control packets latency, the power budget and capacity. The results point out that it is feasible to establish a networking strategy on-demand to support the transmission of continuous IoT data flows with limited overhead.

期刊介绍： The proposed journal, called the IEEE Transactions on Network Science and Engineering (TNSE), is committed to timely publishing of peer-reviewed technical articles that deal with the theory and applications of network science and the interconnections among the elements in a system that form a network. In particular, the IEEE Transactions on Network Science and Engineering publishes articles on understanding, prediction, and control of structures and behaviors of networks at the fundamental level. The types of networks covered include physical or engineered networks, information networks, biological networks, semantic networks, economic networks, social networks, and ecological networks. Aimed at discovering common principles that govern network structures, network functionalities and behaviors of networks, the journal seeks articles on understanding, prediction, and control of structures and behaviors of networks. Another trans-disciplinary focus of the IEEE Transactions on Network Science and Engineering is the interactions between and co-evolution of different genres of networks.
