An Evolution Model for P2P File-Sharing Networks
Jing Huang, Baoqun Yin, Dong Guo, Shan Lu, Xu-min Wu · 2010
Propose an evolution model for Peer-to-Peer (P2P) file-sharing systems, which try to capture the dynamic properties of P2P application networks. The model consists of four events: node joining, node departure, connection establishing and connection breaking, which captures the most important events in constructing network topology. The evolution model results in a differential equation about degree distribution, which can be solved analytically. By analyzing the solutions, some interesting results can be got.
