Wireless sensor networks are an attractive field of researchers for several applications like industrial automation and environmental monitoring and military surveillances. Energy scarcity is a major issue on sensor networks. To meet out the requirement at various power management protocols are proposed by several researchers. Different cluster-based schemes are discussed as a solution for this problem. In this paper, analysis of the present-day classification and general grouping of clustering schemes are studied. It furthermore surveys different energy efficient clustering algorithms with QoS service enhancements.
