摘要: 针对无线传感器网络中存在多种因素影响节点可信的问题,提出了节点路由向量阈;在基于信誉的信任管理框架(RFSN)模型的基础上,采用节点路由向量阈方法,建立了多因素信任的无线传感器信任模型。该模型综合利用通信信任、能量信任和路由向量信任来计算节点信任度,较客观真实地反映出节点的信任程度,应对无线传感器网络遇到的多种安全威胁。仿真实验表明,该模型能更准确地识别节点是否可信,可及早发现恶意节点,延长了网络生存期。

Abstract: For the problem that there are multiple factors affect the node trust, this paper proposes node routing vector threshold; based on RFSN(Reputation-based framework for high integrity sensor networks) model,multiple factors trust model for wireless sensor networks is established by using routing vector threshold. Communication trust, energy trust and routing vector trust are all considered during the computation of node trust in this model. It could objectively show the degree of trust of a node and respond a variety of security threats which wireless sensor networks encountered. Simulation results show that the model can more accurately identify the node trust, detect the malicious node early and prolong the networks' lifetime.

Key words: Wireless Sensor Networks(WSNs), communication trust, energy trust, routing vector trust, trust model
