摘要: 网络的传输性能在一定程度上依赖于网络的拓扑结构。本文从结构信息的角度分析复杂网络的传输动力学行为，寻找影响网络传输容量的信息结构测度指标。通信序列熵可以有效地量化网络的整体结构信息，为了表征网络整体传输能力, 把通信序列熵引入到复杂网络拥塞产生现象中，研究网络的通信序列熵与传输性能之间的关联特性，分析了这种相关性存在的内在机理。分别在BA无标度和WS小世界网络模型上进行仿真，结果显示：网络的通信序列熵与其传输容量存在密切关联性，随着通信序列熵的增加，网络拓扑结构的均匀性随之增强，传输容量明显增加。网络的传输容量是通信序列熵的单调递增函数, 与通信序列熵成正关联关系。网络的通信序列熵可有效评估网络的传输容量，本结论可以为设计高传输容量网络提供理论依据。
Abstract: The transmission performance of the network depends to a certain extent on the topology of the network. This article analyzes the transmission dynamics of complex networks from the perspective of structural information, and looks for information structure measurement indicators that affect network transmission capacity. Existing research shows that the communicability sequence entropy of complex networks can effectively quantify the overall structure of the network. Based on this measurement, the difference between networks can be effectively quantified, and the connotation of sequence entropy of communicability can be explained. Communica- tion sequence entropy can effectively quantify the overall structure information of the network. In order to characterize the overall transmission capacity of the network, the communication sequence entropy is introduced into the phenomenon of complex network congestion, the correlation between the network communication sequence entropy and the transmission performance is studied, and
