Energy harvesting for the Internet-of-Things: Measurements and probability models

Abstract

The success of future Internet-of-Things (IoT) based application deployments depends on the ability of wireless sensor platforms to sustain uninterrupted operation based on environmental energy harvesting. In this paper, we deploy a multitransducer platform for photovoltaic and piezoelectric energy harvesting and collect raw data about the harvested power in commonly-encountered outdoor and indoor scenarios. We couple the generated power profiles with probability mixture models and make our data and processing code freely available to the research community for wireless sensors and IoT-oriented applications. Our aim is to provide data-driven probability models that characterize the energy production process, which will substantially facilitate the coupling of energy harvesting statistics with energy consumption models for processing and transceiver designs within upcoming IoT deployments.

A Smart Energy Harvesting Platform for Wireless Sensor Network Applications

“…Similar to this work, in [11], a hybrid storage system using both rechargeable batteries and supercapacitors with solar energy harvesters architecture is introduced, while in [12] an efficient platform with multiple energy sources as input is proposed and is validated in a WSN surveillance implementation. In [13] a multi-transducer platform for piezoelectric and solar harvesting technologies for both indoor and outdoor use is deployed. The authors in [14] present an energy harvesting wireless sensor node, called Sparrow, which can offer an autonomous, energy harvesting WSN.…”

Modelling of Indoor Light Energy Harvesting for IoT

“…Due to this, IoT devices requires their batteries to be changed frequently, hence the usage of batteries is infeasible. Thus, the technology of environmental energy harvesting can be utilized to improve the sustainability of IoT devices without relying on the batteries [4][5][6]. Generally, IoT devices only require a small amount of power.…”

“…Além disso, a utilização da proposta Internet das Coisas, torna possível o sistema de monitoramento possuir alta adaptabilidade, já que a adição de novos instrumentos de medida é de simples implementação. Um sistema de monitoramento tem de ser escalável e fácil de usar (SMART et al, 2016). Também é tido que a utilização da transmissão de dados sem fios e a robustez que o sistema agregará fazem com que a proposta do trabalho esteja bem situada no conceito de IoT (SMART et al, 2016).…”
