Energy prediction based trust manangement in hierarchical sensor networks

Trust has been recently suggested as an effective security mechanism for wireless sensor networks (WSNs). In this paper, we propose an energy prediction based trust management 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 to detect denial of service (DoS) attacks when nodes are electing trusted clusters. Also we present the scheme performance by simulations. The results show clear advantages of our trust approach in defending against denial of service (DoS) attacks in WSNs.
