Abstract
Today, intelligence in all walks of life is developing at an unexpectedly fast speed. The complexity of the Internet of Things (IoT) big data system of intelligent parks is analyzed to unify the information transmission of various industries, such as smart transportation, smart library, and smart medicine, thereby diminishing information islands. The traditional IoT systems are analyzed; on this basis, a relay node is added to the transmission path of the data information, and an intelligent park IoT big data system is constructed based on relay cooperation with a total of three hops. Finally, the IoT big data system is simulated and tested to verify its complexity. Results of energy efficiency analysis suggest that when the power dividing factor is 0.5, 0.1, and 0.9, the energy efficiency of the IoT big data system first increases and then decreases as α0 increases, where the maximum value appears when α0 is about 7 J. Results of outage probability analysis demonstrate that the system’s simulation result is basically the same as that of the theoretical result. Under the same environment, the more hop paths the system has, the more the number of relays is; moreover, the larger the fading index m, the better the system performance, and the lower the outage possibility. Results of transmission accuracy analysis reveal that the IoT big data system can provide a result that is the closest to the actual result when the successful data transmission probability is 100%, and the parameter λ values are between 0.01 and 0.05; in the meantime, the delay of successful data transmission is reduced gradually. In summary, the wireless relay cooperation transmission technology can reduce the outage probability and data transmission delay probability of the IoT big data system in the intelligent park by adding the multihop path, thereby improving the system performance. The above results can provide an experimental basis for exploring the complexity of IoT systems in intelligent parks.

With the rapid advancement of big data technology, Wang et al (2021) established a data management system to link international academic research and city-level management policies. They increased the number of uses based on the practicality of the collected data to enhance smart cities and the development efficiency of the parks [22]. Various new technologies such as cloud computing, IoT, big data, and artificial intelligence are widely accepted in various industries, they do not have information interoperability, resulting in information islands. erefore, adding a wireless relay cooperation transmission system to the traditional IoT system can provide a basis for the information transmission of intelligent parks, which is of great value to the development of the economy and society
Summary
Technologies such as the Internet of ings (IoT), cloud computing, big data, and mobile IoT have gradually been employed in various industries as science and technology advance forward. e economic level of the entire human society has been greatly improved. The management and service methods of intelligent parks should be based on the demands of people and meet the needs of the public, society, and government as much as possible. IoT has become the core symbol of smart cities and intelligent parks in the “Internet +” era as it gradually penetrates various industries. Adopting IoT cannot contribute to intelligent park construction Instead, this process requires big data analysis and cloud computing technologies. Erefore, it is vital to collect and process data and information while constructing intelligent parks. The wireless relay cooperation transmission technology is added to the traditional IoT systems, and an IoT big data system for intelligent parks is constructed based on relay cooperation. The complexity of the system’s performance is verified through simulation, which can provide a reference basis for the development of intelligent parks in the future
