Abstract: 〖JP2〗With different way of link established, the high frequency IP wide-area network shows a different topological feature during the network operation process. Modeling study and simulation analysis were made with a modified harmonious unifying hybrid preferential model on high frequency IP wide-area network. And the results were found that the degree distribution, shortest path and clustering coefficient would be impacted by the different node selection method for new connection. Mean-while, the average shortest path of the network would be affected by the different edge deletion method. What's more the topological characteristics of the network were determined by the proportion of different node selection method.〖JP〗

Key words: high frequency IP wide-area network, complex network theory, degree distribution, shortest path, clustering coefficient

摘要： 短波IP广域网在网络运行过程中不同的连接建立方式将使网络展现出不同的拓扑特性。结合修正的大统一混合网络模型对短波IP广域网进行建模研究和仿真分析。发现网络的增长过程中新建边上节点选择方式将会影响网络节点度分布、网络平均最短路径长度和聚集系数大小，同时边删除策略的不同同样会对网络的平均最短路径长度产生影响。而在多种节点选择方式情况下，不同方式所占比例将决定网络拓扑特性的发展方向。
