35. 35 Computer Engineering and Networks Technische Informatik und Kommunikationsnetze Prototype Strategy Try to make use of synergies between platforms: Testbed used for all projects. Use and extension of PermaSense base-station in Open- Sense (mobile air pollution measurements). Reuse of PermaSense sensor node in X-Sense (temperature, pressure, crack meters). Development of a new (modular) node concept to be used in PermaSense III (acoustics), X-Sense (location). Maybe Arm/Cortex-based (with energy scavenging)? The SwissEx data backend will be extended towards Open- Sense. Try to use this for PermaSense III and X-Sense or develop a new one that can be used for all projects.
