Projects

Wireless Compose 2: Ballistocardiography for Extraterrestrial Applications and long-Term missions
For the demonstration, Wireless Compose-2 will operate several experiments, with a specific focus on the scientific and medical BEAT (Ballistocardiography for Extraterrestrial Applications and long-Term missions) experiment on ISS
TRIPLE-nanoAUV: Building access to outer planetary oceans
TRIPLE stands for – Technologies for Rapid Ice Penetration and subglacial Lake Exploration.

Past Projects

REAP: Robuste, energieeffiziente drahtlose Sensornetze für realistische Außeneinsatzszenarien durch Adaption von Betriebs-Parametern (DFG: BU 3282/2-1)
Monitoring the changing environmental conditions allows to benefit from the systems dynamics. Realistic models for energy and reliability will be derived from these measurements. Combined with the knowledge about the characteristics of the nodes in the network, this information can, e.g., be used for routing decisions, task scheduling, and processing within the network.
PotatoNet: Outdoor Testbed zur Evaluation drahtloser Sensornetze unter realen Umgebungsbedingungen
Das PotatoNet ist ein Versuchsaufbau, welcher es erlaubt Hardware und Routingprotokolle von selbstentwickelten Sensorknoten unter realen, zum Teil extremen, Betriebsbedingungen zu untersuchen.
INGA: Inexpensive Node for General Applications
INGA is an open source wireless sensor node for anything. INGA was developed at IBR (TU Braunschweig) as Inexpensive Node for General Applications and is used in numerous projects. The motivation to develop INGA was driven by the need for a reasonable, cheap and expandable node for several use cases.
5GSatOpt: Building access to outer planetary oceans
Das Projekt 5GSatOpt behandelt die Integration von Satellitenkonstellationen kleiner Satelliten mit 5G.
