—Network coordinate (NC) system is an efficient mechanism to predict Internet distance (latency) with limited times of measurement. In this paper, we focus on the node churn problem in distributed NC systems. Our study on Vivaldi, a representative distributed NC system, shows that under high node churn rate the prediction accuracy of the system will be(More)
A Network Coordinate (NC) system is an efficient mechanism to predict Internet distance with scalable measurements. In this paper, we focus on the node churn problem – the continuous process of nodes arrival and departure – in distributed applications. Studies on Vivaldi, a representative distributed NC system, show that under node churn the prediction(More)
