中文摘要：

针对无线mesh网混合簇结构的特殊网络环境提出了一种信任模型，该模型将同一个Mesh路由器覆盖范围内的客户端节点看作以Mesh路由器为簇头的簇，节点间的信任关系被划分成5种类型，并采用灰色预测及蚁群算法分别给出了各类信任关系的信任度计算方法。仿真实验结果表明：该信任模型能有效地抵御策略恶意节点的攻击及合谋欺诈攻击，使系统保持较高的分组传输率。

英文摘要：

A trust model was established for wireless＇mesh network~s cluster-based hierarchical archi- tecture. In the model, mesh clients covered by the same mesh router formed a cluster with the mesh router as its cluster head. Trust relations between different mesh nodes falled into five types. Then, the method of calculating each type of trust relation was proposed based on grey forecasting and ant colony optimization. The simulation results show that the proposed model can not only resist the sim- ple and collusive attack from the malicious nodes effectively, but also detect the malicious cluster head so as to maintain the high block transmission rate of the system.
