| 摘 要： | 现有的基于信誉的信任模型对于节点在进行信誉反馈时的行为突然改变不能做出迅速反应,针对该问题,在保留TBRM(mast-bascd reputatlion model)优势的基础上,提出了一种改进的基于信誉的信任模型.该模型引入了惩罚因子加大对节点在进行信誉反馈时的动态摇摆行为的惩罚力度,并且细化了模型的分布式存储策略.仿真实验结果表明,在P2P文件共享网络中,该模型能有效遏制恶意节点的动态摇摆行为,提高真实文件的下载成功率.

| Abstract: | Aimed at the existing reputation-based trust model can not provide rapid reaction to sudden changes in peer's behavior when the peer provide reputation feedback. An improved reputation-based trust model in P2P environment is proposed. This model retained the advantages of TBRM (trust-based reputation model). Punishment factor is introduced to increase the punishment degree on the malicious peers'oscillating behavior when they provide reputation feedback,and the model's distributed implementation scheme is e... |
