在实现电池寿命、信息准确性、传输距离和成本等严格设计目标方面的挑战推动了对传统电池供电设备的能量采集传感器节点的深入研究。当传感器网络需要跨越诸如农田和偏远地形的广阔区域时，远程通信的固有功率密集性质进一步放大了这一挑战。太阳能是无线传感器节点的常见能源，然而，由于季节变化和天气条件引起的功率波动，太阳能并不可靠。本文解决了这些问题，提出了一个永久供电，能量收集传感器节点，利用最小尺寸的太阳能电池，并能够通过动态协同优化能源消耗和信息传输，称为能量信息动态协同优化（EICO）的远程通信。这种能量信息智能是通过基于从收集器和电荷存储元件可用的能量总量的信息传输的自适应占空比来实现的，以优化传感器节点的能量消耗，同时采用传感器内分析（ISA）来最小化信息的丢失。这是第一个被报道的尺寸<35 cm 2的传感器节点，它能够以高达1包/秒的连续信息传送率在> 1 Km上进行远程通信，这是由EICO和ISA实现的。
英文摘要：
Intensive research on energy harvested sensor nodes with traditional battery powered devices has been driven by the challenges in achieving the stringent design goals of battery lifetime, information accuracy, transmission distance, and cost. This challenge is further amplified by the inherent power intensive nature of long-range communication when sensor networks are required to span vast areas such as agricultural fields and remote terrain. Solar power is a common energy source is wireless sensor nodes, however, it is not reliable due to fluctuations in power stemming from the changing seasons and weather conditions. This paper tackles these issues by presenting a perpetually-powered, energy-harvesting sensor node which utilizes a minimally sized solar cell and is capable of long range communication by dynamically co-optimizing energy consumption and information transfer, termed as Energy-Information Dynamic Co-Optimization (EICO). This energy-information intelligence is achieved by adaptive duty cycling of information transfer based on the total amount of energy available from the harvester and charge storage element to optimize the energy consumption of the sensor node, while employing in-sensor analytics (ISA) to minimize loss of information. This is the first reported sensor node < 35cm2 in dimension, which is capable of long-range communication over > 1Km at continuous information transfer rates of upto 1 packet/second which is enabled by EICO and ISA.
