| Abstract | Micro Aerial Vehicles (MAVs) are small flying robots often equipped with on-board cameras, GPS, and other sensors, and enable a manifold of novel civilian services. Surveillance of large farmlands, 3D mapping of an area, as well as search and rescue (SAR) missions are just a few of the growing number of applications. To make use of the information gathered by MAVs, connectivity between the MAVs and the ground stations has to be provided. The MAVs themselves may therefore create an aerial vehicle network. Ad-hoc networking solutions are available, yet, in MAV networks, standard wireless communication technologies are challenged by frequent MAV movement, signal obstruction by the MAV frame, and antenna type as well as orientation influencing signal propagation, that result in intermittent connectivity. Here, traditional mobile ad-hoc routing protocols do not perform well as they require end-to-end connectivity, and pure delay-tolerant networking (DTN) approaches are not optimized for MAV networks. At the same time, MAVs also provide unique opportunities ranging from availability of location and motion sensors to controlled mobility, that are not available in conventional networks, and can benefit wireless communications. Overall, the dimensions of these challenges and opportunities are not a-priori clear. In this dissertation, we propose MAV networking solutions following an empirical approach. We develop and make use of a testbed optimized for the SWARMIX research project on technology-enhanced search and rescue operations. First, we investigate the single aerial link using a platform consisting of two popular types of MAVs, micro airplanes and quadcopters. We characterize the throughput of a link as a function of distance between MAVs communicating through IEEE 802.11n, and further study the impact of major parameters on aerial communications. We also counteract signal obstruction by the MAV frame and antenna-caused impairments by adapting the MAV |
