Structural analysis of complex networks from the mobile Internet

Mobile Internet is one of the most popular networks in the world. Constructing the physical structure of mobile Internet is the key to modeling the network. The existing studies of fixed Internet are not suitable for mobile Internet and a deep understanding of traffic graph in mobile Internet is required. In this paper, we construct a user-server network graphs from the complete flow records of mobile Internet collected from our self-developed equipment deployed in southern China. We investigate the characteristics of the properties of Web, IM and overall traffic as the complex network point of view. Different types of traffic have different characteristics. In addition, node degree and node strength distribution of servers show that mobile network follow the power law, however, node degree and node strength distribution of users do not possess the power law property. We further study the distributions of average strength for each edge of node which follow the power law, and find the regular pattern of exponents for different applications. These discoveries could be used by the ISPs and researchers to optimize the deployment of network resources and enhance the security of the network and the Quality of Services(QoS).
