Abstract
After autonomous flight for Unmanned Aerial Vehicles (UAVs) has been accomplished,
research was stipulated to look into application related challenges in connection with Unmanned
Aerial Systems (UAS). As one possible scenario, swarms of collaborating UAVs
can be envisioned and allow for more complex missions and scenarios.
One essential building block in simultaneously operating several UAVs is the UAS internal
and external communication. Ground control station operators need to communicate
guidance, navigation, and control (GNC) data, external beneficiaries of the UAS operation
need to be provided with obtained sensor data and intelligence. All this requires sophisticated
wireless communication networks and Mobile Ad-hoc Networks (MANETs) step
into the picture.
However, evaluating the performance of different MANETs in a UAS environment is
non-trivial: relevant metrics and evaluation procedures have to be established for a simulation
based performance prediction during the design phase of a MANET. Unfortunately,
published results on MANET performance are not necessarily comparable across different
papers, due to differences in the underlying assumptions. Some findings might not even
be applicable to a UAS environment.
This paper proposes a set of reference scenarios in order to allow for comparable and
applicable results in MANET simulations. The presented scenarios mimic realistic UAS
missions, both, on the operational side of the participating network nodes, as well as on the
network traffic side. The reference scenarios capture the essence of current UAVs and UAS
missions in a civil, research, or military context, hence providing the means to simulate
different MANET protocols in a UAS setting.
