Abstract
Self-organized networks such as mobile ad-hoc, Internet-based peer-to-peer, wireless mesh
and Fourth Generation (4G) Wireless networks depend on cooperation of nodes. Reputation
systems help nodes decide with whom to cooperate and which nodes to avoid. They have
been studied and applied almost separately in diverse disciplines such as economics, computer
science and social science, resulting in effort duplication and inconsistent terminology. In
this paper, we aim at bringing together these efforts by outlining features and fundamental
questions common to reputation systems in general. We derive methodologies to address these
questions and lessons for both reputation system design and research from our own experiences
and evaluations by simulation and analytical modelling. We argue for using deviation tests,
discounting, only passing on of first-hand information, secondary response, and stressing the
importance of identity.
