Test and validation of wireless IoT using testbeds


Jan Beutel
Researcher at NES group, University of Innsbruck


Networked embedded systems such as Wireless Sensor Networks, Internet of Things applications or Cyberphysical Systems are typically implemented on resource limited devices. The intricacies of systems operating at their resource limits, e.g. memory or power, the distributed nature and the tightly integrated within a certain application domain require to test and validate such systems in a realistic setting. To this extent testbeds have become the de-facto popular medium of choice. In this talk we will shortly review their evolution and then demonstrate several of our own developments leading to the most recent end-member: FlockLab 2, a second generation testbed sup-porting multi-modal, high-accuracy and high-dynamic range measurements of power and logic timing and at the same time in-situ debug and trace infrastructure of modern microcontrollers allowing for reproducible evaluation and benchmarking. We detail the architecture, provide a characterization and demonstrate the interface based on examples from academic research as well as real-world applications.
