Models and Games for Data Dissemination in Peer-to-Peer Systems

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.
