Most existing clustering protocols have been aimed to provide balancing the residual energy of each node and maximizing lifetime of wireless sensor networks. In this paper, we present the symmetric hierarchical clustering strategy related to sink position and energy threshold in wireless sensor networks. This protocol allows networks topology to be adaptive to the change of the sink position by using symmetrical clustering that restricts the growth of clusters based on depth of the tree. In addition, it also guarantees each cluster has the equal lifetime, which may be extended compared with the existing clustering protocols. We evaluated the performance of our clustering scheme comparing to existing protocols, and our protocol is observed to outperform existing protocols in terms of energy consumption and longevity of the network.
