摘要
基于通信的信任模型不能完全解决无线传感器网络面临的安全威胁和节点能量不足的问题。提出一种基于节点通信、数据和能量相结合的信任模型,将传感数据和节点能量加入节点信任评估因素中,通过不同的信任计算方法得出各自的信任值,建立一个节点更加可信的无线传感器网络。模拟实验结果表明,基于通信一种因素的信任模型不足以决定一个节点的可信性,基于多角度的信任模型能够更简单、准确地判断一个节点的可信性。
The trust model based on communication can not completely solve the problems of security threats and lack of energy in wireless sensor networks. A trust model based on communication, data and energy was proposed in this paper, which added the sensing data and the node＇s energy in the factors of trust assessment, and used different methods to calculate the separate trust values. By this way, a wireless sensor network of node more reliable could be established. Simulation results show that, one model only based on communication trust is not enough to decide on the trustworthiness of a node, and the model based on multi-angle trust can judge the credibility of a node more simply and accurately.
