| Abstract | With the rapid development and deep application and cooperation of new concepts and technologies brought by the Internet of Things and cloud computing all over the world, all walks of life have gradually moved towards a "smart" modem society. These technologies have gradually penetrated into the field of smart cities. The traditional urban system, the system that has been handed down since ancient times, has a very inefficient and cumbersome mode of operation, and the information between the systems has not been effectively shared and interconnected. In order to solve this series of problems, this study first studies the development of the Internet of Things, cloud computing-related technologies and smart cities, and then focuses on the key technologies of the Internet of Things and cloud computing in the field of structure and application. Under the support of these two technologies, proposed a smart city system based on Internet and cloud computing. System architecture, application system design, application support platform, various transmission networks and typical sensors are studied in detail and on different levels. In smart city systems based on the Internet of Things, sensor networks are often placed in unreliable communication environments, and this usually causes the transmission of information to fail. Whether the sensor chooses to transmit again after the information transmission fails is an optimized problem. This research study proposes a data aggregation algorithm based on Markov chain to solve the problem of transmitting such data again. The experimental results show that the system can realize information sharing, exchange and fusion between various sensing subsystems, solve the previous information island phenomenon and meet the actual needs of smart cities. |
