| Abstract: By harvesting friendship
networks from e-mail contacts or instant message ``buddy lists''
Peer-to-Peer (P2P) applications can improve performance in low
trust environments such as the Internet. However, natural social
networks are not always suitable, reliable or available. We propose
an algorithm (SLACER) that allows peer nodes to create and manage
their own friendship networks. We evaluate performance using a
canonical test application, requiring cooperation between peers for
socially optimal outcomes. The Artificial Social Networks (ASN)
produced are connected, cooperative and robust - possessing many of
the disable properties of human friendship networks such as trust
between friends (directly linked peers) and short paths linking
everyone via a chain of friends. In addition to new application
possibilities, SLACER could supply ASN to P2P applications that
currently depend on human social networks thus transforming them
into fully autonomous, self-managing systems. |
