基于信任机制的无线传感器网络结构

Framework for trust-based mechanism in Wireless Sensor Network

一个恶意节点或一个妥协节点当选为簇头节点是基于簇的无线传感器网络要应对的最重要的问题之一。当恶意者进行一个重大的攻击行动时,个别节点可能易于被攻陷,因此要设计一种能消除潜在的重大安全破坏的结构和机制,阻止这些妥协节点当选为簇头节点。介绍一个分布式的基于信任的框架和一个信任簇头选举机制,提出的机制减少了恶意节点或妥协节点被选为簇头的可能性。采用仿真验证所提出的方法和模型,结果清晰地显示出该方案在阻止非信任节点成为簇头节点方面的强大优势。

The election of a malicious or compromised node as the cluster head is one of the most significant breaches in cluster-based Wireless Sensor Network （WSN）.While a significant vulnerability is addressed,individual nodes may still be prone to attack.Thus this paper introduces a framework and a mechanism to eliminate the potentially significant security breach and prevents the election of compromised cluster heads.In light of this,the paper introduces a distributed trust-based framework and a mechanism for the election of trustworthy cluster heads.The mechanism reduces the likelihood of compromised or malicious nodes from being selected as cluster heads.The approach and the model are evaluated by simulations.The results indicate clear advantages of the approach in preventing the election of untrustworthy cluster heads.
