中文摘要: 在无线传感器网络环境下,由于信任关系的随机性、模糊性和不可预测性等不确定性因素给网络交易带来了诸多安全问题。以无线传感器网络环境为研究背景,引入云模型理论,提出一种基于簇结构无线传感器网络的云信任评价模型,实现了信任属性的定性概念与定量数值之间的转换。该模型模拟LEACH路由协议,根据传感器自身特性评价节点的信任值,准确识别自私节点。通过仿真实验证明了该模型能对节点准确而客观的评价,为无线传感器网络环境下信任评价的研究提供了一个新的思路。
Abstract:In the wireless sensor network environment, the randomness, fuzziness,and unpredict-ability bring a lot of secure issues to network transactions. In order to treat this problem, by using cloud model theory, the trust model based on cluster structure was proposed. This trust evaluation approach can implement the conversion between qualitative and quantitative of trust attributes. The model simulated LEACH routing protocol, evaluating trust value of the nodes according to their own characters and can identify of selfish nodes accurately. The simulation results showed that the model can accurately and objectively evaluate the nodes, and the cloud trust model proposed here may provide a new promising method for research of trust evaluation in wireless sensor networks environment.
