| Research Abstract |
In order to estimate P2P video delivery method in real environments, we proposed a method based on supervised learning, so-called the weighted k-nearest neighbor (WKNN) algorithm, for estimation of overlay link qualities from qualities observed in the past. Our experiments on PlanetLab showed that our method has good performance on path latency estimation, and there is no correlation between overlay links with close geographical similarity on bandwidth estimation.
