Considering the befitting potential of communication for CPS applications, following are a few questions that we focus on at the Research Days 2019.
- Which communication technologies can be used for explicit and implicit CPS swarm communication (including terrestrial, aerial, aquatic CPS applications)
- How important is connectivity for swarming?
- Distributed vs centralized vs decentralized
- How could every member be autonomous in terms of connectivity?
- What are the communication parameters a CPS swarm designer needs to take care of when choosing a communication technology?
- How to standardize CPS data structures and define protocols to enable a unified CPS communication language compatible for all potential available communication technologies?
- What are the potential research challenges that need to addressed to use communication for CPS swarm related to autonomy?

“Together Everyone Achieves More! On Swarm Performance and Interference”
Together we achieve more! Is that also true for swarms? Physical and communication interference but also contention can decrease group and swarm performance. We have a look on how to determine good group sizes and on how to make scalability robust. The scalability properties of robot swarms have astonishing similarities to those of distributed computing, communication networks, and even natural systems. With a better understanding of how group performance scales with group size, we can maybe develop more efficient systems. We end by studying an approach to develop swarm systems that scale robustly.

“Sense and Avoid Technology for enabling Swarms”
Autonomous drones are becoming a reality, and we will see swarms of drones probably before the first truly autonomous car. To enable this, drones need to be aware of each other and their environment. We have been working on the SESAR project PercEvite, aiming to create sense and avoid technology for small autonomous drones. In this talk, I will discuss the state of the art with respect to sense and avoid technology and how to enable it on a range of vehicles: from small lightweight drones to manned aircrafts even.
Sofie Pollin is associate professor at KU Leuven and active in the domain of wireless communication for drones for more than 5 years now. She has experience with a wide range of technologies and tested them all on drones (from Wi-Fi to 5G), and is especially focused on enabling autonomous and lightweight drones for civilian applications.

“Communication in Swarms: Forms, Strengths, and Limitations “
Technological advances in communication, embedded computing, energy storage, sensors and actuators enable an increasingly higher number of potential applications for swarms of robots. In order to be competitive, such swarm systems should show a certain degree of coordination capability and scalability in terms of number of nodes. To achieve such properties, the choice (or design) of the inter-node communication forms (e.g., indirect, direct, broadcast, peer-to-peer) plays a key role. However, physical channels and protocols for communication cannot be chosen independently from other system design choices, in particular when the individual robotic nodes are constrained in their resources by cost, volume, or mass considerations imposed by the targeted application and/or the specific environment in which they have to operate. In this talk, I will leverage a few case studies we carried out in our laboratory and results from the literature to illustrate forms of communication implemented up to date in physical robotic swarms, analyze their strength and limitations, and propose some practical lessons that we learned over more than twenty years of research to address the communication problems in distributed robotic systems.
Alcherio Martinoli has a M.Sc. in Electrical Engineering from the Swiss Federal Institute of Technology in Zurich (ETHZ), and a Ph.D. in Computer Science from the Swiss Federal Institute of Technology in Lausanne (EPFL). He is currently an Associate Professor at EPFL, leading the Distributed Intelligent Systems and Algorithms Laboratory. Before joining EPFL he carried out research activities at the Institute of Biomedical Engineering of the ETHZ, at the Institute of Industrial Automation of the Spanish Research Council in Madrid, Spain, and at the California Institute of Technology, Pasadena, U.S.A. His research interests focus on methods to design, control, model, and optimize distributed cyber-physical systems, including multi-robot systems, sensor and actuator networks, and intelligent vehicles.

“Direct and Indirect Communications in Swarms and Their Effects”
We describe our three dynamically coevolving multigraph model of networked systems and swarms. We demonstrate it use to find effective communication patterns and organization to speed up distributed decision-making and actions in swarms. We investigate the significance of the resulting patterns regarding resilience and robustness in swarm coordination. We show how direct and indirect communications can lead to simple and efficient coordination and control strategies. We compare with communication patterns in biology from birds and ants. We consider and solve inverse problems whereby we determine the communication and collaboration patterns of swarms by discovering symmetries and invariances in their trajectories.

“Communication and Drones”
The commercial market for applications enabled by small drones is growing rapidly. Such applications pose different communication constraints, such as desired throughput, delay tolerance, range, and connectivity, which may be hard to fulfill in mobile aerial networks. We present an application-layer rate-adaptive multicast video streaming framework over an aerial testbed of IEEE 802.11a ad-hoc network. We then evaluate the performance of 802.11ac – a newer addition to the 802.11 family, for an aerial mesh network. Furthermore, we present an Android-based cellular drone measurement tool and evaluate LTE performance for drone networks. Lastly, we introduce the forthcoming 5G playground Carinthia and our “Communication in Swarms” use case.

Selection of appropriate funding instruments for research projects is a critical task and often vital for successful commencement and accomplishment of R&D actions. This talk focusses on presenting current and future funding opportunities on national (Esp. Austria), cross-national and European level. As far as available, we will also present information on the new European frame programme “Horizon Europe” (successor of Horizon 2020). The goal of the talk is also to give funding directions for project ideas arising during the course of this year’s Research Days.
