FlockLab 2: Multi-Modal Testing and Validation for Wireless IoT

Abstract

The development, evaluation, and comparison of wireless IoT and cyber-physical systems requires testbeds supporting inspection of logical states and accurate observations of physical performance metrics.We present FlockLab 2, a second generation testbed supporting 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, the supported services and the tools of the FlockLab 2 testbed.
