摘要
P2P流媒体系统中自私节点的不合作行为严重破坏了P2P流媒体系统的整体性能.分析了Habib等人提出的基于等级的鼓励用户贡献转发资源的激励机制的缺陷,提出了一种改进的基于等级的激励机制.仿真实验结果表明,改进后的算法具有更好的性能,能更有效的抑制自私节点的行为.
The existence of selfish and malicious peers and their non-collaborative behaviors heavily damage the whole performance of the peer-to-peer system.Making an analysis to a rank-based incentive mechanism which was proposed by Habib,found that there were some deficiencies in this incentive mechanism.Thus,an improved rank-based incentive mechanism was proposed which could urge selfish peers to behave collaboratively.The preliminary results verify that the improved incentive mechanism provides a good quality of service and availably control the behaviors of selfish peers.
