| 摘 要： | 为了在无线传感器网络可靠性研究中对故障检测等容错机制进行准确评价和量化分析,有必要进行网络故障模型的研究。该文提出了1种具有高覆盖度特点的网络层次化故障模型。在4种网络故障类型研究基础上利用图论方法提出面向节点层和子网络层的层次化故障模型设计方法,基于复杂网络聚类系数给出1个面向故障模型的单点型关键节点判定定理,并以此为例通过子模型有效性原则对该类模型进行了证明,结果表明该故障模型有效。

| Abstract: | A high coverage hierarchical fault model was developed to accurately evaluate fault-tolerant mechanisms of wireless sensor networks.Graph theory is used to design a fault model oriented to the node and sub-network levels.A network fault key node is defined in a sub-network,with a theorem given to evaluate a single type key node based on its complex network clustering coefficient.The sub-model effectiveness principle is used to show that the hierarchical fault model is effective. |
