论文摘要
安全是工业无线传感器网络（IWSN）的主要问题之一。为了确保群集IWSN中的安全性，本文通过模糊信任评估和离群值检测（SCFTO）提出了一个安全的聚类协议（SCFTO）。首先，为了处理开放无线介质中的传输不确定性，采用间隔2型模糊逻辑控制器来估计信任。然后引入了基于密度的离群检测机制，以获取用于隔离群集头的自适应信任阈值。最后，提出了一种基于模糊的集群头选举方法，以在节能和安全保证之间达到平衡，以便具有更剩余能量或对其他节点置信度更高的正常传感器节点具有更高的可能性，使其成为群集头的可能性更高。广泛的实验验证我们的安全聚类协议可以有效地捍卫网络免受内部恶意或受损节点的攻击。
Security is one of the major concerns in Industrial Wireless Sensor Networks (IWSNs). To assure the security in clustered IWSNs, this paper presents a secure clustering protocol with fuzzy trust evaluation and outlier detection (SCFTO). Firstly, to deal with the transmission uncertainty in an open wireless medium, an interval type-2 fuzzy logic controller is adopted to estimate the trusts. And then a density based outlier detection mechanism is introduced to acquire an adaptive trust threshold used to isolate the malicious nodes from being cluster heads. Finally, a fuzzy based cluster heads election method is proposed to achieve a balance between energy saving and security assurance, so that a normal sensor node with more residual energy or less confidence on other nodes has higher probability to be the cluster head. Extensive experiments verify that our secure clustering protocol can effectively defend the network against attacks from internal malicious or compromised nodes.
