Analysis to reveal evolution and topological features of a real mobile social network

With the rapid advance of mobile devices, the mobile social networks (MSNs) have emerged to provide mobile social users with diverse content services. However, due to the ever increasing number of mobile social users, the evolution and topological features of MSNs should be studied for optimization. Therefore, based on the realistic trace data this paper studies the evolution and topological features of the MSNs. Firstly, the evolution feature of the MSN when time changes is discussed. Then, the topological features such as degree distribution, node distance, node closeness, and betweenness are studied. In addition, experiment results show how the MSN changes over time and prove that the MSN is a scale-free network with strong small-world features.
