In this paper, the authors present a detailed survey on various techniques used for cluster formation and load balancing algorithms to improve the lifetime of the WSN so that it can be extended to reasonable times. There are many reasons where energy will be drained rapidly. Some situations like improper formation of a cluster and also due to traffic, the energy will be consumed more and lifetime of the sensor node will be limited. So, they present a systematic and comprehensive taxonomy for the selection of cluster head, which are discussed in subsequent sections.
