摘要
为了改进P2P的激励机制,运用间接互惠的思想提出了一种分布式名誉更新机制,改进了一种尝试性疏通算法.该机制避免了偶发错误对合作的影响,能够快速地达到较高的下载速率,激励参与节点尽力提供资源.运用演化博弈理论证明了参与节点以最大物理带宽上载是演化稳定策略.
This paper designed a distributed reputation updating mechanism based on indirect reciprocity, and improves an algorithm of attemptable unchoked. Accidental mistakes are avoided to influence cooperation among individual participants, it can reach high downloading rate quickly, and individual participants are incented to offer resources sharing. With the theory of evolution games, it is proved that all individual participants upload with their highest physical bandwidth is an evolutionary stable strategy.
