A decision-analytic approach for P2P cooperation policy setting

Abstract

While overall performance of peer-to-peer systems depends strongly on the amount of resource contributions made by individual peers, autonomous and rational peers make decisions on their cooperation policies (resource contributions) according to their individual utilities. To deal with the inherent conflict among individual utilities of the rational peers to improve overall performance of the system, we propose a decision-analytic approach that determines the appropriate cooperation policies of the individual peers in a distributed manner and coordinates their rational decisions in compliance with the social welfare improvement.
