UAV Networks and Communications, Cambridge University Press, edited by Kamesh Namuduri, University of North Texas, Serge Chaumette, Université de Bordeaux, Jae H. Kim, Boeing Research and Technology, and James P.G. Sterbenz, University of Kansas is available for Pre-order.
This is the first book to focus on communications and networking aspects of UAVs. It covers the foundational concepts of the topic, as well as offering a detailed insight into the state of the art in UAVs and UAV networks, discussing the regulations, policies, and procedures for deployment (including analysis of risks and rewards), along with demonstrations, test-beds, and practical real-world applications in areas such as wildlife detection and emergency communications.
Samira Hayat and I have co-authored the chapter entitled “Aerial Wi-Fi Networks“, which identifies the characteristics of aerial links and communication requirements for an aerial network. A special focus is given to IEEE 802.11 (Wi-Fi) technologies due to their wide availability in current networking devices, their suitability for small UAVs, and the extensive research dedicated to them in the past decades. We report real-world measurements for multi-hop aerial Wi-Fi networks and discuss the feasibility of this communication technology to deliver the required quality of service for several potential applications.
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.

You can find information on our current and previous projects and our publications, in addition to posts from guest researchers.
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.
