22nd GI/ITG KuVS expert discussion on sensor networks

Wireless sensor networks, the Internet of Things (IoT) and cyber-physical systems (CPS) have a lot in common: they consist of sensors that collect and exchange data in order to control and optimize complex processes. Their areas of application extend across various sectors such as smart spaces, Industry 4.0, intelligent energy grids and medical care. Sensor networks enable real-time monitoring, increased efficiency and improved decision-making. They play a central role in creating intelligent, connected environments that make everyday life easier and transform industry. Thanks to their versatility and innovative power, sensor networks have become a key element in the digital transformation, blurring the boundaries between the physical and digital worlds.

The expert discussion on sensor networks offers a unique platform for exchanging ideas about sensor networks in the scientific community.

Sensor networks, also known as the Internet of Things (IoT) or cyber-physical systems (CPS), are key components of the digital revolution. They consist of a large number of networked sensors that can record, analyze and exchange data. The importance of sensor networks extends across numerous fields of application, including smart cities, Industry 4.0, healthcare and agriculture. Technical challenges in the implementation of sensor networks include data security and privacy, energy efficiency, interoperability and scalability. Despite these challenges, sensor networks are crucial for the transformation of various industries and play a key role in shaping a connected and digitized future.

The FGSN facilitates the exchange on sensor network technologies, investigations of sensor network characteristics, applications of sensor networks and related topics. All contributions to the design, implementation, evaluation and application of sensor networks are welcome. The FGSN has established itself as a particularly suitable platform for receiving feedback on doctoral projects.

The program committee of the expert discussion Sensor Networks 2025 included

• Thomas Hänel, University of Osnabrück
• Florian Klingler, TU Ilmenau
• Silvia Krug, Mid Sweden University
• Ulf Kulau, TU Hamburg
• Krzysztof Piotrowski, BTU Cottbus and Leibniz Institute for Innovative Microelectronics (IHP)

The FGSN 2025 took place on 11 and 12 September at Clausthal University of Technology in the rooms of the CUTEC Center (room M 2.31 in Leibnizstr. 23).

With a population of 12,000, Clausthal-Zellerfeld is one of the smallest university locations in Germany. There are several hotels, guest houses, vacation apartments (including AirBnB) and a youth hostel on site.

There are many tourist activities in the Oberharz region around Clausthal-Zellerfeld and the imperial city of Goslar, a 20-minute drive away, not least the two UNESCO World Heritage Sites "Oberharzer Wasserregal" (consisting of 107 historic ponds and ditches with a total length of 310 km) as well as the old town of Goslar and the Rammelsberg visitor mine.
