Decentralized Schemes for Size Estimation in Large and Dynamic Groups
by Dionysios Kostoulas, Dimitrios Psaltoulis, Indranil Gupta, Ken Birman, Al Demers — 2005 — In proc. of the 4 th IEEE International Symposium on Network Computing and Applications (NCA’05
…Large-scale and dynamically changing distributed systems such as the Grid, peer-to-peer overlays, etc., need to collect several kinds of global statistics in a decentralized manner. In this paper, we tackle a specific statistic collection problem called Group Size Estimation, for estimating the numb…

Practical algorithms for Size estimation in Large and Dynamic groups
by Contact Person, Dimitrios Psaltoulis, Dimitrios Psaltoulis, Dionysios Kostoulas, Dionysios Kostoulas, Indranil Gupta, Indranil Gupta, Indranil Gupta, Ken Birman, Ken Birman, Al Demers, Al Demers
…present in the group at a given point of time. The problem is related to aggregation, and several solutions have been proposed. In this paper, we present two new sampling-based algorithms for estimation in dynamic groups (i.e., where processes are constantly joining and crashing), and thoroughly …
