Miniature implementation of an IoT‐based smart city

Abstract

Ever since the idea of a Smart City was introduced, the Internet of Things (IoT) has been a key pillar of the technological aspect of Smart City development. Cities should fully grasp the advantages and opportunities of the IoT for Smart Cities since there is so much promise and opportunity in a wide variety of fields, including traffic management, urban mobility, security and healthcare. This project presents a scalable miniature implementation of an IoT‐based smart city model, using three physical nodes that perform air quality monitoring, parking sensing, and fire detection. The nodes communicate with a centralised server using NB‐IoT and CoAP protocols. The data ingested from said nodes is stored and visualised using InfluxDB and Grafana. The project evaluates the system from different perspectives, such as integration, load, and battery consumption. Integration testing indicated that all system components integrate properly with each other. Load testing demonstrated that the system can handle a reasonable number of requests without performance degradation. Battery consumption tests indicate that the physical nodes’ battery life lasts for several days.
