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...

Wireless sensor networks (WSNs) require an extremely energy-efficient design. As sensor nodes have limited power sources, the problem of autonomy is crucial. Energy harvesting provides a potential solution to this problem. However, as current energy harvesters produce only a small amount of energy and their storage capacity is limited,...

In this paper, we propose a global power management approach for energy harvesting sensor nodes. Our approach is based on a joint duty-cycle optimization and transmission power control. By simultaneously adapting both parameters, the node can maximize the number of transmitted packets while respecting the limited and time-varying amount of...
