SubCounter:一种基于语义簇聚的节点子集规模估计方法
SubCounter: A Node Subset Size Estimation Approach Based on Semantic Clustering
摘要
Abstract
Many P2P applications need the size values of node subsets in the system to enhance performance. The existing subset size estimation approaches are based on applying the size estimation approach directly. This paper proposes SubCounter, a node subset size estimation approach based on semantic clustering. SubCounter maintains a semantic clustering neighbor list for each node by view exchange, so each node can keep contacts with others in the same subset. Based on the semantic clustering, SubCounter realizes the estimation of subset sizes, through anti-entropy aggregation. The experimental results show that compared with the existing approaches, SubCounter converges more quickly when each node belongs to many subsets simultaneously, and ensures the same precision and similar robustness with less communication and storage cost.关键词
