一种基于感知模型的P2P MMOG信任模型

Trust Model Based on Awareness Model for P2P MMOG

根据P2P MMOG的特点提出一种适合其应用的基于感知模型的信任模型。该模型中玩家仅对处于其感知范围内的玩家进行信任评估,使用滑动窗口对玩家信任度进行更新,并使用模糊综合评判对玩家多粒度信任度进行合并。实验结果表明,该模型不仅能保证信任评估的精确性还能有效节省评估对系统资源的使用,并能真实反映玩家信任度的变化,可以为P2PMMOG的安全提供更好的支持。

A trust model based on awareness model was proposed which was suitable for the application of P2P MMOG according to the Characteristics of it. With this model, a player only evaluated the reputation of other players in his awareness area. Players＇ trust was updated by slide window, and players＇ multi-granularity trust was aggregated by fuzzy synthetic evaluation. The simulation results show that this model can not only guarantee the accuracy of trust evaluation but also save the usage of system resources for evaluation effectively, and can reflect the changes of trust actually. This model could offer better support for security of P2P MMOG.
