Unmanned autonomous systems are increasingly used in a large number of contexts to support humans in dangerous and difficult-to-reach environments: e.g. ground-based robotics, aerial sensor systems, space and underwater applications. In order to fulfill particularly challenging tasks, visionary scenarios foresee unmanned vehicles to be organized in networked teams and even swarms. The corresponding wireless networks need to provide highly reliable and delay-tolerant control links for the management of the behavior of the unmanned vehicles as well as data links to reliably transfer telemetry and sensor data respectively. At the same time, unmanned vehicles offer the capability to provide ad-hoc wireless networks, for example to facilitate temporary hot spots and compensate network outages in case of public events and emergencies. This fifth edition of the workshop aims to discuss most recent results of various international research projects on new communications networks enabling the efficient control of teams of unmanned vehicles/systems operating on the ground, in the air, underwater and in space scenarios. Contributions addressing heterogeneous scenarios, e.g. combination of aerial and underwater devices are highly welcome.
