The intention of this evaluation was to show whether undervolting is usable for WSNs or not. For this purpose we deployed PotatoNet and performed a long-term study of about 4 months. The WSN was continuously toggled between an undervolted state and a state where all nodes were powered by the recommended voltage level. Within each state, every node broadcasted a message on 16 different tx-levels. Every event (IdealVolting output, transmitted messages, received messages) were logged by the central box for post-processing.
The PotatoNet was deployed on a trial field from the VSD research station for potato crops. Hence, our evaluation was performed in the light of a real-world Smart Farming application with farming and harvesting activities.
All data that have been collected during this evaluation are available for download here.
Some interesting pictures from construction, deployment and operation of Potatonet can be found in our gallery.
