EICO: Energy-Harvesting Long-Range Environmental Sensor Nodes With Energy-Information Dynamic Co-Optimization

Intensive research on energy-harvested sensor nodes has been driven by the challenges in achieving stringent design goals of battery lifetime, information accuracy, transmission distance, and cost. This challenge is further amplified inherent power-intensive nature long-range communication when networks are required to span vast areas, such as agricultural fields remote terrain. Solar power a common energy source wireless nodes, however, it not reliable due fluctuations available stemming from changing seasons weather conditions. article tackles these issues presenting perpetually powered, energy-harvesting node which utilizes minimally sized solar cell capable dynamically co-optimizing consumption transfer, termed energy-information dynamic co-optimization (EICO). intelligence achieved adaptive dutycycling transfer based total amount harvester charge storage element optimize node, while employing in-sensor analytics (ISA) minimize loss information. first reported < 35 cm2 dimension, over >1 km at continuous rates up 1 packet/second enabled EICO ISA.
