    "abstract": "This paper presents a statistical analysis of the structure of Peer-to-Peer\n(P2P) social networks that captures social associations of distributed peers in\nresource sharing. Peer social networks appear to be mainly composed of pure\nresource providers that guarantee high resource availability and reliability of\nP2P systems. The major peers that both provide and request resources are only a\nsmall fraction. The connectivity between peers, including undirected, directed\n(out and in) and weighted connections, is scale-free and the social networks of\nall peers and major peers are small world networks. The analysis also confirms\nthat peer social networks show in general disassortative correlations, except\nthat active providers are connected between each other and by active\nrequesters. The study presented in this paper gives a better understanding of\npeer relationships in resource sharing, which may help a better design of\nfuture P2P networks and open the path to the study of transport processes on\ntop of real P2P topologies.",
