基于能量敏感的无线传感器网络信任度计算模型

由于无线传感器网络开放性、动态性等特点,导致整个网络易受攻击而极为脆弱,给传统安全机制带来严峻挑战,从而限制了无线传感器网络的发展。作为对基于密码体系的安全手段的重要补充,信任管理在解决来自网络的内部攻击,识别恶意节点、自私节点及低竞争力节点方面有着显著的优势。本文将节点的能量信息引入节点信任度计算模型中,提高了系统安全性、可靠性和公平性。通过仿真分析说明,模型以较少的资源消耗对网络的资源配置、性能、安全和通信进行统一的维护和管理,能够保证网络正常有效地运行,既缓解了WSN的管理困难,也为信任应用研究开辟了新的途径。

Based on Energy-sensitive Trust Calculation Model in Wireless Sensor Networks

Due to wireless Sensor Networks’ openness,dynamic characteristics,resulting in the entire network vulnerable to attack and extremely weak,pose serious challenges to the traditional security mechanisms,thus limiting the development of wireless sensor networks.As an important supplement to cryptography based security solutions,trust management has significant advantages in terms of resolve internal attacks from the network to identify malicious nodes,selfish nodes,and low competitiveness of nodes.Node energy information is introduced into node trust calculation model and the model can improve system security,reliability and fairness.the simulation analysis shows that the model can manage and maintain the resources,performance,fault,security and communication with fewer resources consumption to ensure the effective operation of networks.The model not only alleviates the WSN management difficulties,but also opens up new avenues for trust application research.
