连接的无线设备数量的巨大增长导致对网络连接的需求不断增加。在这种情况下，空中网络可以通过扩大接入网络的概念而发挥重要作用。本文描述和分析了无人机在通信领域最有前途的应用之一：通过部署空中通信网络来扩展无线系统的容量或覆盖范围。我们提出了一个全面的表征研究的实验系统部署空中WiFi网络。为此，英特尔Galileo开发板被适当配置和配备为WiFi节点，在基础设施模式中扮演接入点的角色，或在ad-hoc操作模式中扮演中间跳的角色。然后将该设备集成到无人机上。我们比较两种WiFi模式的覆盖面积，吞吐量和能源效率。初步结果表明，在覆盖范围和数据速率之间存在权衡，基础设施模式表现更好，而能源效率，ad-hoc模式更具响应性。
The huge growth in the number of connected wireless devices leads to an increasing demand for network connectivity. In this context, aerial networks may play an important role by widening the concept of access networks. This paper describes and analyzes one of the most promising applications of Unmanned Aerial Vehicles, commonly known as drones, in the field of communications: Extending the capacity or coverage of wireless systems through the deployment of aerial communication networks. We present a comprehensive characterization study of an experimental system to deploy an aerial WiFi network. To do so, an Intel Galileo development board is appropriately configured and equipped as a WiFi node playing either the role of an access point in the infrastructure mode or of an intermediate hop in the ad-hoc operational mode. This device is then integrated onboard a drone. We compare both WiFi modes in terms of coverage area, throughput, and energy efficiency. Preliminary results reveal that there is a trade-off between coverage and data rates, for which the infrastructure mode performs better, and energy efficiency, where the ad-hoc mode is more responsive.
