分簇结构战术互联网中信任评估模型研究

Trust evaluation model in cluster-based tactical Internet

通过对现有典型信任评估方案进行分析比较,提出了分簇战术互联网中基于隶属云理论的信任评估方案,给出了簇内信任和簇间信任的建立、合成与更新公式。方案基于分簇的网络结构,将大量的信任信息限制在簇内,有效减少了实体的存储和控制开销,降低了能量损耗,延长网络生存时间,更加适合于战术互联网环境。

Basing on analyzing some typical trust evaluation schemes,this paper presented a cloud theory based trust evaluation scheme in cluster-based tactical Internet and introduced the establishment,composition and updating formula of trust between entities intra and inter cluster.With the use of clustering,restrained most trust information in cluster,thus cuts down the cost of store and control,reduced energy consumption and then prolonged the network duration.The proposed scheme is much more suitable for Tactical Internet environment.
