In current peer-to-peer systems, system performance is evaluated by the metrics that characterize the features of the whole system while how each node's character affects the system performance is rarely considered. In this paper, we first introduce a new metric of publishing efficiency to quantitatively measure the impact of node's character on the system performance, and also we demonstrate the...
In current peer-to-peer (P2P) systems, system performance is evaluated by the metrics that characterize the features of the whole system while how each node in system affects the system performance is rarely considered. In this paper, we first introduce a new metric of publishing efficiency based on the impact of nodes' characters on the system performance. Then, we build an analytical model to study...
A large number of resource locating algorithms have been proposed in peer-to-peer (P2P) networks. However, the query efficiency of most existing methods is limited to large-scale P2P networks. In this paper, we propose a new decentralized P2P architecture, by taking advantage of the heterogeneous characters of nodes to integrate the resources of stable nodes, and simplify the management of dynamic...
