Our paper entitled “Drone Networks: Communications, Coordination, and Sensing” is accepted for publication in Ad Hoc Networks Journal.
In this paper, we describe a high-level architecture for the design of a collaborative aerial system consisting of drones with on-board sensors and embedded processing, sensing, coordination, and communication and networking capabilities. We implement a multi-drone system consisting of quadcopters and demonstrate its potential in disaster assistance and area monitoring scenarios. Furthermore, we illustrate design challenges and present potential solutions based on the lessons learned so far.
Our research at Klagenfurt focuses on many civil applications of drones. The following video illustrates the functionalities we can enable on quadrotor platforms tailored for disaster response. Specifically, we show multi-drone coordination supporting aerial surveillance, target detection, video streaming, delivery, navigation under forest canopy and human-drone interaction.
Our survey entitled “Survey on Unmanned Aerial Vehicle Networks for Civil Applications: A Communications Viewpoint” is accepted in IEEE Communications Surveys and Tutorials.
This comprehensive survey reports the characteristics and requirements of UAV networks for envisioned civil applications over the period 2000–2015 from a communications and networking viewpoint. We survey and quantify quality-of service requirements, network-relevant mission parameters, data requirements, and the minimum data to be transmitted over the network. Furthermore, we elaborate on general networking related requirements such as connectivity, adaptability, safety, privacy, security, and scalability. We also report experimental results from many projects and investigate the suitability of existing communication technologies for supporting reliable aerial networking.
We have tested our multi-UAV system for a search and rescue scenario, where we have demonstrated the planning, communication, and detection capabilities of the aerial network. Once the target is detected, a communication relay chain is formed from the UAVs to the ground station, streaming real-time video of the target. See the video of the demo here.
Our paper, “Experimental Performance Analysis of Two-Hop Aerial 802.11 Networks” is accepted in IEEE Wireless Communication and Networking Conference 2014.
The paper focuses on deployment of standard WLAN technology for different network setups over an aerial network. It is experienced that certain setups not only offer network range extension, but also much lower variance in throughput. It is also seen that the standard routing protocol for 802.11s mesh lacks vastly in its implementation when applied to multihop aerial networks. Thus, there is a need to evaluate alternative mesh routing protocols that cater for aerial communication network demands.
Christian Bettstetter and I have organized the Sixth Lakeside Research Days on Multi-UAV Systems. The event was hosted by Lakeside Labs and the University of Klagenfurt in Klagenfurt, Austria, from July 8 to 12, 2013.
