The Power of Models: Modeling Power Consumption for IoT Devices

Abstract

Making more energy efficient technologies is still far from having those envisaged ubiquitous deployments (so called the Internet of Things, or the Industrial Internet), which will enable optimal industrial operation, and will contribute to improve the social welfare.Today, it is possible to build a device which features this industrial wireless performance, and is able to in-node analyze the acquired data. However, energy-dimensioning the device in order to meet the application requirements is not an easy task, especially when the reliability claimed for industrial applications faces up to the uncertainty introduced by energy harvesting.Modeling and dimensioning the energy consumption of an application at pre-deployment or pre-production stages is of utmost importance considering the critical requirements of IoT applications in terms of reduced cost, life-time, and available energy. This paper presents a comprehensive model for the power consumption of wireless sensor nodes that accounts for all the energy expenditures at system-level: communications, acquisition and processing. The model is only based on parameters that can be empirically quantified, once the platform (i.e., technology) and the application (i.e., operation conditions) are defined. This results in a new framework for the study and analysis the energy live-cycle within the applications, suitable to determine in advance the specific weight of application parameters and to understand the tolerance margins and trade-offs in the system.

Development of an Indoor Photovoltaic Energy Harvesting Module for Autonomous Sensors in Building Air Quality Applications

“…To keep the IoT node working continuously, the start voltage of the next measurement period should not be lower than Vt1. According to the energy flow model [25], the total energy harvested ∫ =0 should be greater than the energy…”

IoT‐Based Management Platform for Real‐Time Spectrum and Energy Optimization of Broadcasting Networks

“…The transceiver operational modes are as follows ( Figure 5): sleep, receiving, and transmitting [36]. LoRa transceivers have a power consumption in sleep mode of just 0.33 W [37] and NB-IoT transceiver 3 mW [18].…”

“…Besides the transceiver, the IoT end-devices have other power consuming components: the data acquisition system and the digital signal processing [36]. As the acquisition system and digital signal processing are already included by the digital TV receiver hardware because of its functionality we assume no additional power is required to retrieve and to process the data by the STB.…”
