Power Consumption Analysis of Wireless IoT Devices

Over the past decade, Internet of Things (IoT) has become a widely recognized technology. IoT systems continue to grow exponentially, but power and energy consumption remain as one of the most important aspects of implementing IoT at scale. As IoT technology expands, the demand for large-scale data collection requires rapid processing, storage, retrieval, and communication protocols. Big data can be retrieved by a large number of IoT devices with different collection, processing, and communication capabilities. Reliability, scalability, and deployment capabilities of wireless IoT systems depend on critical design and minimizing power consumption. This is especially true for IoT devices that are self-powered, use local energy storage or energy harvesting systems. Replacing and maintaining large scale battery- powered IoT systems with a large number of individual devices can prove to be prohibitively expensive or extremely time-consuming. Therefore, the importance of extending the usable uptime of IoT devices is leading to an increasing demand for the implementation of specialized electronics as well as the development of communication protocols that can further reduce device energy consumption. In this study, the power consumption and energy requirements of wireless IoT devices, communication systems and protocols deployed in smart cities and in the transportation sector are compared and analyzed.
