A WSN is made of one or numerous distant sinks and numerous minute, low-power sensors, apiece equipped with actuators, sensing devices, and wireless transmitters and receivers. Sensors are generally power-driven by smaller batteries. The sink is normally static and located outside the network. This results in the increase of the communication distance between the far away cluster heads from the sink. These spent higher energies than those located close to sink. In order to balance the energy, this paper displays various clustering approaches that makes the use of the mobile sink to collect data from the cluster heads.
