Wireless Sensor Networks (WSNs), since their introduction in the control active systems during the last decade, have been extensively studied for their wireless connectivity and their remote sensing capacities. Yet, WSNs are far from being implemented to their full potential: the energy harvesting capacity of each individual node requires improvement, the computation power of every sensing node is currently under-exploited and despite their distributed architecture, WSNs are still used in centralized paradigm. In this paper, we present a node of WSN able to both sense its environment and harvest energy from the same signal and we introduce the distributed capacity of the resulting global Wireless Sensor Network.
