构建能量敏感的无线传感器网络信任模型

摘要

In order to build a model that is high-efficiency, expandable and reliability in the environment of Wireless Sensor Network, the trust model of WSNs have been studied, and put forward a trust model which is sensitive to energy. This model constructs a new risk-trust model, and generalizes the factors of remaining energy to the value of trust model at the same time. Thus, combine the trust of communication and the trust of energy skillfully, considering the secure factor more seriously and building a more safe and authentic model of WSNs. Proved by simulation experiment and analysis, this model can recognize vicious nodes, the successful rate of trading by nodes quickly and highly improve the security of information in the network system when compared with other models, which consumedly strengthened the stability and the safety of the system.%为在无线传感器网络环境中构建一个高效、可扩展和安全的信任模型,研究了无线传感器网络信任模型,并提出了一种能量敏感的无线传感器网络信任模型.该模型构建了一种新的风险信誉关系模型,并将剩余能量因素推广到信任值中,将通信信任和能量信任结合在一起,全面的考虑了网络的安全因素,建立了一个更加安全、可信的无线传感器网络.仿真实验和分析证明,该模型较其他模型,能够更快的识别出恶意节点,在节点交易成功率和网络系统信息的安全性方面都有较大的提高,大大增强了系统的稳定性和安全性.
