Abstract

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.

无人机上的WiFi网络

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。在这方面，空中网络可以通过扩大接入网的概念发挥重要作用。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。我们提出了一个实验系统的全面表征研究，以部署空中WiFi网络。为此，英特尔伽利略开发板被适当地配置和装备为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点的角色。然后将该设备集成到无人机上。我们比较了两种WiFi模式的覆盖范围、吞吐量和能源效率。初步结果表明，在覆盖率和数据速率之间存在权衡，其中基础设施模式表现更好，而能源效率，其中ad-hoc模式响应更快。
