针对异构无线网络的不确定性和动态性,提出一种基于实体可信度的动态信任模型.利用待测实体可信度和推荐主体可信度抑制恶意实体的破坏行为,采用信任时间戳标志信任信息的时间特性,突出近期信任信息的重要性.仿真结果表明,该模型能准确、有效地确定网络实体的信任度,较好抑制诋毁行为和协同欺骗行为.
針對異構無線網絡的不確定性和動態性,提齣一種基于實體可信度的動態信任模型.利用待測實體可信度和推薦主體可信度抑製噁意實體的破壞行為,採用信任時間戳標誌信任信息的時間特性,突齣近期信任信息的重要性.倣真結果錶明,該模型能準確、有效地確定網絡實體的信任度,較好抑製詆燬行為和協同欺騙行為.

Aiming at the characteristics of uncertainty and variability in heterogeneous wireless network, this paper proposes a dynamic trust model based on entity credibility. By introducing credibility of the candidate network and credibility of the evaluating entity, malicious behaviors of the dishonest entities are restrained effectively. Time stamp makes the evaluation pay much attention to the most recent performance records. Simulation result shows that the model can accurately evaluate the trustworthiness of the network and effectively restrain the acts of slander and co-fraud.
