天空的网格：为地面物联网提供无处不在的连接
The Meshing of the Sky: Delivering Ubiquitous Connectivity to Ground Internet of Things
摘要：
如今，无人机（UAV）正被用于一些新的应用，特别是在电信领域。然而，确保用于特定应用目的的无人机通信和联网仍然具有挑战性。实际上，由于UAV在广阔区域中的移动性，回程上的永久连接是非常零星的并且可能丢失。在本文中，我们考虑了一个空中网状网络，其中每个无人机可以作为一个飞行基站，以提高地面基站的情况下，损坏的基础设施的情况下，例如，或/和提供连接未覆盖或覆盖不良的节点，并作为一个中继建立两个组件之间的通信，由于它们之间缺乏可靠的直接通信链路。然后，我们详细介绍了一个案例研究，其中无人机机队用于从地面物联网（IoT）设备收集数据，并将其转发到云，以便通过远程网关进行进一步处理。我们的目标是建立一个包括网络层、MAC层和物理层的路由框架，并研究上行链路和下行链路的通信链路。接下来，我们推导出一些封闭的形式，使我们能够预测网络性能的空中网状网络，端到端（E2 E）的吞吐量和e2 e延迟的每个无人机的流量强度。接下来，我们进行广泛的模拟，以说明我们的框架的好处。结果讨论和许多见解的参数设置，目标服务质量和设计考虑也提请。
英文摘要：
Nowadays, Unmanned Aerial Vehicles (UAVs) are being used in several novel applications, especially in the telecommunication domain. However, ensuring UAV communication and networking for the purpose of a specific application is still challenging. Indeed, due to the mobility of a UAV in a vast area, permanent connectivity over the back-haul is very sporadic and might be lost. In this paper, we consider an aerial mesh network where each UAV can serve as a flying base station to boost terrestrial base station in case of damaged infrastructure case for example, or/and provide connectivity for uncovered or poorly covered nodes, and behaves as a relay to establish communication between two components owing to a lack of reliable direct communication link between them. We then detail a case study where a UAV-fleet are used to collect data from the ground Internet of Things (IoT) devices and forward it to cloud for further processing passing by a remote gateway. We aim here to build a queueing framework including network layer, MAC layer, and physical layer and investigate both uplink and downlink communication links. Next, we derive some closed forms allowing us to predict the network performance in terms of traffic intensity at every UAV of the aerial mesh network, end-to-end (E2E) throughput and e2e delay of ongoing streams. Next, we conduct extensive simulations to illustrate the benefit of our framework. Results discussion and numerous insights on parameter setting, target quality of service and design consideration are also drawn.
