This paper applies the theory of social networks to P2P systems, creating a social-network-based P2P network topology … searching and for relaying shared files between network leafs that are located behind Firewalls/NATs. The topology of the P2P … network is based on the actual social relationship between peers (users). The idea is that users are willing to contribute …

simple evolutionary network model that explains this difference. The results of our model suggest that there are two reasons …. Second, boundaries between subgroups (groups of network nodes) distort the degree distribution. In general, we believe that … network design recommendations in a variety of areas such as WWW-hyperlink networks, business collaboration networks, Peer …

In order to overcome the problem of free-riding in current P2P system, we suggest applying social network theory. Based … framework within this paper. It specifies social network information that can be used in a P2P system to avoid performance … inefficiencies caused by free-riding or by policies to overcome free-riding. To identify this specific social network information, we …

A node of the Web2.0 service network ….0 service network can be understood as an innovation system that creates value through the composition of services, representing … the collective intelligence of users. Within this paper, we analyze the openness of the Web2.0 service network. Openness …

In this study, we develop a theoretical model based on social network theories and analytical methods for exploring … collaboration (co-authorship) networks of scholars. We use measures from social network analysis (SNA) (i.e., normalized degree … students instead of other well-performing scholars. Consequently, we can state that the professional social network of …

Since this Web2.0 service network is constructed without the control of a single entity (i.e., it is self-organizing), the … network topology of the Web2.0 service network shows the scale-free characteristic.
