Abstract
Recently, the widespread adoption of the Internet of Things (IoT) and machine-to-machine (M2M) has led to a significant influx of smart services and applications. This research paper addresses the deployment and implementation of IoT/M2M technologies in the smart city, one of its most popular applications. The proposed solution presents a complete system for IoT/M2M smart cities based on different mobile cellular networks (MCNs) such as 2G, 4G, or 5G; to provide safety, convenience, energy saving, and urban quality of life improvement by using efficient and low-cost components such as Arduino microcontroller and NodeMCU board with several compatible sensors, actuators, and shields. The purpose of this paper is to present a practical example of an IoT/M2M smart city system; that contains several smart applications such as smart safety that consists of three services (fire and gas detection, air quality monitoring system, and automatic railway crossing system), smart agriculture and smart parking. All these applications are designed and implemented to control and monitor the city remotely via our mobile application called “Raniso,” which provides citizens with essential daily urban services in a simple and accessible way. The app also serves as a communication platform between citizens and city authorities, facilitating collaborative processes and digital participation within the smart city.
