Advances in computing, communications, and sensor technologies are creating new opportunities to exploit low-cost instrumentation for widespread and long-term environmental observation. Because a tethered energy infrastructure is usually not available ...

Fine-grained energy metering in homes and buildings provides a promising technique for addressing the unmaintainable energy consumption levels of worldwide buildings. Metering electricity, lighting, natural gas, HVAC, occupancy, and water on a per ...

Street lighting can enhance the safety and security of residential and commercial areas. However, its installation and operation is expensive: cables must be installed, and power is drawn from the grid which is typically dominated by non-renewable ...

Future Internet of Things is paving the way for the proliferation of Wireless Sensor Networks (WSNs). To overcome the limited energy in batteries, WSN nodes are relying on everlasting environmental energy. Moreover, a Power Manager (PM) is also embedded ...

Energy harvesting offers wireless sensor networks the possibility of indefinite operation. Their energy sources are typically uncontrollable and exhibit significant temporal-spatial variation. Traditional approaches to managing their operation have been ...

With increasing demand of long term applications, supercapacitors have been widely chosen as energy storage devices for energy harvesting aware wireless sensor networks( WSNs) due to their long charging-discharging life cycles. However, few studies have ...

The problem of designing and simulating optimal communication protocols for energy harvesting wireless networks has recently received considerable attention, thus requiring an accurate modeling of the energy harvesting process and a consequent redesign ...

Combining local harvest patterns and global weather forecasts, e.g., cloud-cover forecasts, makes solar harvest predictions and online duty cycle adaptation more reliable. For this purpose, an energy and bandwidth efficient network-wide distribution of ...

We propose an approach to energy-neutral operation by Wi-Fi beamforming for wearable devices to achieve energy-neutral operation. We take advantage of the transmit beamforming feature of IEEE 802.11ac's multiple input, single output (MISO) structure to ...
