Smart City and the Use of Internet of Things in It
摘要
The global urban population is expected to rise from 55 to 68% by 2050, adding 2.5 billion people in the next three decades. Managing this growth requires a focus on social, economic, and environmental sustainability, leading to the concept of smart cities. Utilizing communication and information technology, smart cities deploy an Internet of Things (IoT) framework, connecting objects and machines through wireless technology. Cloud-based IoT applications enhance decision-making for municipalities, companies, and citizens, improving overall quality of life. Key aspects include integrating data with physical infrastructure, optimizing energy distribution, and addressing issues like traffic congestion and waste management. This paper explores IoT methods for smart cities, emphasizing control of urban traffic systems, energy efficiency, and privacy and security. It highlights the main components of smart cities, such as smart lighting, parking, agriculture, waste management, and buildings. Trust is crucial for smart city success, requiring secure access, data integrity, confidentiality, and accountability.
