Making experimental research on low-power wireless networking repeatable, reproducible, and comparable is a long overdue step that hinders a wide acceptance of this technology within the industry. In this paper, we start to fill this gap by proposing and applying a well-defined methodology that specifies how to plan and execute experiments, as well as how to report their results. We further discuss potential definitions for repeatability, replicability, and reproducibility in the context of low-power wireless networking.
