P2P网络中信任机制能够很好地检测和惩罚恶意节点,激励节点之间合作。提出了一种基于生态网络协同进化机理的信任博弈模型,应用复制动态机制分析了节点之间信任关系的长期演化趋势,从理论与实践上说明了在P2P网络中应用此信任模型具有良好的演化稳定性及性能的整体最优性。
The trust mechanism can detect and punish the malicious nodes,and promote honest and cooperative interactions in the P2P networks.In this paper,we present a trust game model based on the evolutionary mechanism of ecological network,and apply the replicator dynamics mechanism to analyze the evolutionary trend of trust relationships among nodes.P2P networks using this model have good performance and stability.
