The authors present the effects of different churn models on the performance of structured Peer-To-Peer (P2P) networks in this paper. Specifically, Exponential Distribution (ED), Pareto Distribution (PD), and Weibull Distribution (WD) are evaluated to provide a comparative analysis. Kademlia-based Peer-to-Peer Protocol (P2PP) is utilized as the underlying signaling protocol. Through simulations, they conclude that the simulated different churn models do not have a significant effect on the performance of the simulated structured P2P network. Quantitatively, ED and PD result in better performance compared to WD from the viewpoints of lookup success rate, mean network traffic load, and mean number of messages.
