Let G be a network with node set V and link set E, where each link e in E is associated with capacity c(e) and failure probability p(e). Let D=(s, t, d) be a flow demand on G which requests that a video stream of bit rate d should be delivered from source node s to sink node t through network G. The reliability of network G with respect to flow demand D is the probability of surviving a subgraph of...
Peer-to-Peer (P2P) systems have attracted considerable attention in recent years, as a key technology to realize scalable, dependable network services. However, because of its high anonymity, P2P systems involve several flaws such as the weakness against malicious attacks by anonymous peers. In this paper, we propose a method to evaluate the trustfulness of each peer by explicitly taking into account...
