手机短信网络的生长过程研究

模拟了短信网络的生长过程并研究其拓扑结构.发现短信网络在生长过程中，度分布、节点的度与其加入网络时间的关系、平均度随时间的变化等方面与先前的模型有所不符.根据短信网络的数据分析，提出了短信网络的生长机制——局部优先连接机制.结果表明，模拟以短信网络为代表的实际网络时，局部优先连接模型优于其他网络模型. 关键词： 复杂网络 短信网络 局部优先连接

Research on the growing process of short message networks

We investigate the growing process and topological features of the short message networks(SMN).Simulations show that the networks' degree distribution,average degree and the correlation between the node's degree and its time in the network are different from those of the former networks models.With due consideration of some of the characteristics of the SMN,we suggest a new type of network growing protocol,namely the local-preference connecting protocol.The numerical results show that the networks generated from our model are more representative in simulating real networks represented by SMN when compared with other network models.
