Cluster head rotation: a proposed method for energy efficiency in d2d communication

In this paper, the authors propose a novel Cluster Head Rotation method to spare the cluster head burden in energy consumption. The clustering method, which is a state-of-the-art approach in D2D communication, is expected to reduce the devices´ energy consumption. However, this method may induce significant energy burden for cluster head, which can bring significant disproportion in cluster head and cluster member energy consumption ratio. The authors performed several simulations to prove the eminence of Cluster Head Rotation. According to our simulation, Cluster Head Rotation achieve a better balance in energy consumption (1.25:1 for CH:CM) compared to standard clustering method (3:1 for CH:CM). Furthermore, the overall energy consumption of Cluster Head Rotation is also 75% lower than standard clustering method.
