英文摘要： This project aims to study the transmission performance of communication network from a network science perspective. In our previous work, we introduce the node usage probability as an effective metric for characterizing the traffic load distribution. In this project, communication network performance is analyzed and optimized based on the concept of node usage probability. The data transmission in the communication network is modelled by incorporating the empirical data and realistic operation settings of real communication networks. Then, the transmission mechanism of communication networks is analyzed through theoretical analysis and computer simulation, the purpose being to further explore the impact of network structure, routing strategy, communication pattern and resource allocation on the communication network performance. Finally, based on the concept of node usage probability, effective network design strategies, including network structure adjustment, routing algorithm design and communication pattern design, can be developed to maintain balanced traffic loads in the network and improve the overall network performance. This project can help to improve the understanding of the transmission mechanism in communication network, and provide important insights for design and optimization of realistic communication networks.
