Technologies contributing to the development of smart cities include Internet of Things (IoT) devices, which facilitate data collection and monitoring of urban systems. These include smart sensors for traffic management, energy efficiency, waste management, and public safety. Additionally, big data analytics plays a crucial role in processing information generated by IoT devices to improve city services and infrastructure. Cloud computing supports data storage and accessibility, while advanced communication networks, such as 5G, enable seamless connectivity. Together, these technologies enhance urban living, sustainability, and resource management.
