Secure cluster formation using two-hop conformity check and broadcast communication

In wireless sensor networks, clustering is frequently adopted because it facilitates the energy savings of nodes and consequently extends the network lifetime. In this paper, we propose a novel and secure cluster formation scheme. First, our scheme generates larger sized clusters to raise the quality of clusters. Second, our scheme produces healthier clusters by evicting more compromised nodes from clusters. Last, our scheme saves the energy of nodes by employing broadcast communication. Simulation results prove that our scheme is more robust against compromised nodes and more energy-efficient than other scheme.
