论文摘要
在这项工作中，我们讨论了将微卫星星座作为地面站之间的通信甚至在物联网情景中“智能”设备之间进行通信的有效基础设施的利用。我们在Omnet ++（带有OS3框架）中设计和实施一系列实验，并在不同的情况下评估其结果。最初，我们建立了空间通信的必要理论背景，包括卫星和星座设计功能，并在各个感兴趣的领域拥有现有和新颖的卫星服务。此外，我们详细介绍了Omnet ++和OS3框架，并为我们的实验介绍了重要的变量/参数。我们的方案分为三个组，与一个直接的一个发件人背道而驰 - 一个接收器通信，并通过多个相邻地面站的拓扑传输了ping。我们以一项物联网案例研究结束，其中我们从Smartsantander测试床的传感器中导入实际测量。通过我们的实验，我们观察了模拟参数的影响，例如星座设计（例如，卫星和平面的数量）以及关于产生的RTT和PING损失的Satellitelinks，同时我们还强调了它们在干扰占主导地位时对网络通信的潜在贡献。
In this work we discuss the utilization of micro-satellite constellations as effective infrastructures for the communication among ground stations or even among 'smart' devices in IoT scenarios. We design and implement a series of experiments in OMNeT++ (with the OS3 framework) and evaluate their results in different scenarios. Initially, we establish the necessary theoretical background for space communications, including satellite and constellation design features, with existing and novel satellite services in various areas of interest. Furthermore, we detail the OMNeT++ and OS3 frameworks and introduce the significant variables/parameters for our experiments. Our scenarios are presented in three groups, departing from the straightforward one sender - one receiver communication and proceeding with a topology of multiple neighboring ground stations transmitting pings. We conclude with an IoT Case Study in which we import real measurements from sensors of the SmartSantander test-bed. Through our experiments we observe the effect of simulation parameters such as the constellation design (e.g., the number of satellites and planes) and the intersatelliteLinks regarding the produced RTT and ping loss, while we also highlight their potential contribution on networking communications when disruptions dominate.
