“Multidrone systems: More than the sum of the parts”, accepted for publication in IEEE Computer, 2021.

Authors: Bernhard Rinner, Christian Bettstetter, Hermann Hellwagner, and Stephan Weiss Abstract: Drones have evolved from bulky research platforms to everyday objects that enable a variety of innovative applications. One of the current challenges is to unite individual drones into an integrated autonomous system. They should operate as a networked team to provide novel functionality that […]
