Chapter in “UAV Networks and Communications”

UAV Networks and Communications, Cambridge University Press edited by Kamesh Namuduri, University of North Texas, Serge Chaumette, titlecoverUniversité 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.

Supporting First Response Personnel with Autonomous Drones

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.

Paper accepted in ICRA 2017

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.

Survey accepted in IEEE Communications Surveys and Tutorials

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.

 

Successful experiments with multiple quadrotors

We have demonstrated a multi-UAV coverage scenario with three quadrotors working together to make an overview image of a large area. The vehicles were equipped with cameras and they followed pre-computed flight paths, taking high-quality pictures at certain points. The collected images were immediately transmitted to a ground station, where the mission progress could be readily overseen and changed if necessary.
