Jie Huang and Bei Huang A security key distribution scheme based on energy efficiency for hybrid wireless sensor networks Security and Communication Networks 7
In this paper, at first, the number range of cluster heads is determined according to the change of the average path length with the probability that the nodes are selected as the cluster heads. Next, a novel security mechanism is respectively proposed for the vital link and the ordinary link. At last, in order to balance the energy consumption over all nodes, a selecting cluster head algorithm is proposed to rotate periodically cluster heads.
