Wireless sensor networks sense data and implements wide range of practical applications development. Although, Wireless Sensor Networks (WSNs) have the capability to be applied to some applications but there is some limitations associated with it in some environments. Energy efficiency is the primary factor in WSN and energy level maintenance is the important problem in distributed sensor networks. Cluster based communications protocols implements the energy efficiency mechanisms in WSN. Cluster Head (CH) selection is the important factor of those protocols.
