AN OPEN-LOOP ENERGY NEUTRAL POWER MANAGER FOR SOLAR HARVESTING WSN

Energy harvesting Wireless Sensor Networks are receiving increasing interest due to their potential to extend system lifetime. Because environmental energy availability is highly variable, an efficient power management is required. An energy harvesting power manager must adapt to different situations that depends on the energy that can be harvested from the environment. In this paper we propose a generic model for solar energy harvesting wireless sensor node, that we validate on real hardware. A novel power management architecture is then proposed. Simulation results show that up to 30% performance improvement can be achieved compared to a state of the art power management algorithm.
