Abstract:

We begin with an overview of incentive systems for cooperation in peer-to-peer file distribution including those that are: based on monetary exchange, based on cumulative reputations, and rule-based. Incentives work for both the process of query resolution (via structured, unstructured or hybrid systems) and for the exchange of data itself. For data-exchange, we will formulate a game involving provably incentive-compatible cumulative reputation systems and uplink-bandwidth control. An epidemiological (coagulation) model for BitTorrent swarms will also be described. Finally, I will conclude with a brief description of epidemiological modeling of the Slammer worm and discuss the quarantined DETER testbed based on Emulab.
