基于能量预测的传感器网络信任机制研究

信任机制最近已建议作为一个无线传感器网络(WSNs)有效的安全机制.文中提出了一种信任机制(EPTM),该机制不仅可以防止被入侵的节点或者恶意节点选举为簇头,而且还设计出一种新型副簇头节点来监察簇头以防止他们的恶意行为.特别介绍了一种基于能量预测的方法来检测拒绝服务攻击(DoS)的节点,选出值得信赖的簇.最后通过仿真验证了机制的可行性,结果表明:EPTM可以有效防御拒绝服务(DoS)攻击.

Research on Energy Prediction Based on Trust Manangement in Wireless Sensor Networks

Trust has been recently suggested as an effective security mechanism for wireless sensor networks(WSNs).In this paper,a trust mechanism(EPTM) is proposed that not only prevents the election of compromised or malicious nodes as cluster heads,but also introduce novel vice-head nodes to monitor the cluster heads’ behaviors in case of their betrayal.Specifically,we employ energy prediction method is emploged to detect denial of service(DoS) attacks when nodes are electing trusted clusters.Also we present the scheme performance by simulations is presented.The results show clear advantages of our trust approach in defending against denial of service(DoS) attacks in WSNs.
