Abstract:
Today, most peer-to-peer networks are based on the assumption that the
participating nodes are cooperative. This works if the nodes are
indifferent or ignorant about the resources they offer, but limits the
usability of peer-to-peer networks to very few scenarios. It
specifically excludes their usage in any non-cooperative peer-to-peer
environment, be it Grid networks or mobile ad-hoc networks. By
introducing soft incentives to offer resources to other nodes, we see
an overall performance gain in traditional file-sharing networks. We
also see soft incentives promoting the convergence of peer-to-peer and
Grid networks, as they increase the predictability of the
participating nodes, and therefore the reliability of the services
provided by the system as a whole. Reliability is what is required by
Grid networks, but missing in peer-to-peer networks.
