摘要
为了实现从安全管理的角度划分移动Ad hoc网络的网络结构,保证移动Ad hoc网络的有效运行和管理,提出了一种信任评估模型.该模型从信任的定义出发,采用实体行为的服务级管理,针对不同类别服务的实体行为表现成功次数和失败次数对信任关系进行度量,定义了直接信任度、推荐信任度和节点信任度.结果表明该模型适用于移动Ad hoc网络,弥补了移动Ad hoc网络中现有的成簇算法缺少恶意节点检测的缺陷.
To partition structurally the mobile Ad hoe network (MANET) in view of its security management and ensure its effective operation and management, a trust valuation model was developed according to the definition of trust. Introducing the service level management of entity behavior and measuring the success/failure frequencies of different kinds of entity behavior in trusting relationship, the direct, recommendation and node trust or confidence is defined separately. The application results showed that the model is adaptive to mobile Ad hoe network and especially it can compensate for the defect that there is no detection to malicious nodes in other existing clustering algorithms.
