论文摘要
随着太空机构正计划载人的任务到达火星,研究人员需要为在旅行期间支持宇航员铺平道路。这也将通过通过无线网络基础架构提供宽带和低延迟连接来实现。在这样的框架中,我们提出了一个三维(3D)网络的火星部署,该网络充当云无线电访问网络(C-RAN)。该方案主要由无人驾驶汽车(UAV)和纳米卫星组成。由于火星的气氛稀薄,立方体可以在非常低空的情况下稳定绕行。这允许满足无人机和立方体之间基带处理功能的严格延迟要求。本文介绍的详细分析研究证实了拟议的3D体系结构的生存能力,在一些限制和关于所涉及的空间通信基础架构的权衡下进行了详细讨论。
As space agencies are planning manned missions to reach Mars, researchers need to pave the way for supporting astronauts during their sojourn. This will also be achieved by providing broadband and low-latency connectivity through wireless network infrastructures. In such a framework, we propose a Martian deployment of a 3-Dimensional (3D) network acting as Cloud Radio Access Network (C-RAN). The scenario consists, mostly, of unmanned aerial vehicles (UAVs) and nanosatellites. Thanks to the thin Martian atmosphere, CubeSats can stably orbit at very-low-altitude. This allows to meet strict delay requirements to split functions of the baseband processing between drones and CubeSats. The detailed analytical study, presented in this paper, confirmed the viability of the proposed 3D architecture, under some constraints and trade-off concerning the involved Space communication infrastructures, that are discussed in detail.
