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 paper entitled “Multi-Objective UAV Path Planning for Search and Rescue” is accepted for publication in IEEE ICRA 2017.
We propose a multi-objective optimization algorithm to allocate tasks and plan paths for a team of UAVs. Our genetic algorithm approach aims to minimize the mission completion time, which includes the time to find the target (area coverage) and the time to setup a communication path (network connectivity). We evaluate strategies using a data mule, a relay chain, and a novel hybrid approach to communicate with the ground personnel. The algorithm can be tuned to prioritize coverage or connectivity, depending on
the mission demands.
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.
I was invited to give a talk at the FLYNET (Micro and Nano Aerial Vehicle Networks for Civilian Use) workshop held at ETH Zurich, 3-5 November 2014.
My talk was entitled “Communication and Cooperation in Multi-UAV Networks”, where I reported our latest results on multi-hop aerial networks using IEEE 802.11a, n, and ac technologies. Slides of my talk are available on request.
I was invited to give a talk at the 2nd AETOS international conference on “Research challenges for future RPAS/UAV systems“. The conference took place in Bordeaux, France, 9-10 September 2014 co-located with UAV Show 2014.
My talk was entitled “Communication and Cooperation in Multi-UAV Networks”, where I talked about our work on multi-UAV systems for civil applications, treating the multi-UAV system as a network of nodes that cooperate toward a common goal such as area coverage or search and rescue, where the team behavior is enabled via communication between the UAVs. Especially, I focused on planning in multi-UAV systems and evaluation of networking behavior via real-world experiments. Slides of my talk are available on request.
