摘要
在现有基于确定性理论P 2P信任模型的基础上,通过引入不同的惩罚参数、树形结构以及反馈机制对模型中存在的不足进行了改进获得新模型,利用文件共享仿真实验证明了新模型的可信性和有效性,该模型对恶意节点具有很好的隔离作用。
Based on the present P2P trust model,a new model is proposed in this paper through the introduction of different penalization parameters and the tree-structure and the improvement of the present model.It is proved that the new model is reliable and effective and that the model performs very well in isolating malicious modes.
