The document discusses how the Internet of Things (IoT) can be used to create smart cities. IoT refers to a network of physical objects embedded with sensors that can connect and exchange data over the internet. A smart city uses digital technologies and IoT to enhance performance, reduce costs and resource consumption, and engage citizens. IoT can be used in smart cities for structural health monitoring of buildings, waste management, air/noise monitoring, traffic management, energy usage analysis, smart parking, smart lighting, and e-health services. The Indian government has allocated funds to develop 100 smart cities using modern technologies like IoT.
