content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....

among structured peer-to-peer systems, chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. however, chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing latency an...

abstract— peer-to-peer ( p2p ) systems have been the center of attention in recent years due to their advantage . since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . this paper investigates the use of genetic ...

We assess social influence on borrowers’ default decisions in a peer-to-peer lending market. Our analysis suggests that online borrowers are significantly influenced by defaults in their social networks. A friend’s default decision more than doubles a user’s default rate. We also find that not all friends have equal influences. The social influence is highly significant among online friends mad...

In a peer-to-peer complex environment, information is permanently diffused. Such an environment can be modeled as graph, where there are flows of information. The interest such modeling that (1) one describe the exchanges through time from initial state network, (2) description used fit real-world case and to perform further forecasts, (3) it trace time. this paper, we review methodology for de...
