A wireless sensor network is used in various applications like military, healthcare application; in our daily life, as well can be seen the applications of a sensor network. The basic characteristic of these sensor nodes are it has limited power and its tiny structure. Because of this energy is the most important concern of WSN. To minimize energy, researchers have developed various ideas. To focus on energy and to improve the network lifetime whole network is partitioned into small areas called a cluster. Clustering plays a very important part in improving the consumption of energy and eventually the network life. In clustering group of sensor nodes create clusters and among them, one A node is selected as a cluster leader(CHs). A cluster head's sense of duty is to aggregate the information from there cluster members and promote it to the sink node. One of the biggest challenges is to select the appropriate cluster head in WSN. In case if a sink is a mobile sink then mobile sink has to move to the head of the cluster to collect the data which cluster head has collected. So it is very much important to find cluster head properly so that the length of a mobile sink tour should be minimized. There are various methods of finding the cluster head.This paper addressed the different methods for selecting a cluster head to minimise the node energy and maximize the lifetime of the network.
