To extend lifetime, significant energy saving to create balanced cluster is a challenge of Wireless Sensor Networks (WSN). Selection of proper Cluster Heads (CHs) is one of a solution to overcome this challenge. Here, we have offered a simple balanced CH selection method that will save significant energy as well as increase lifetime of the network. Our system is centralized. In the offered method, we have considered four parameters i.e. remaining Energy, Number of neighbor nodes, Distance between CHs and Base Station (BS) and One hop neighbor information. Moreover, we have dynamically adjusted distance value by another factor of β for each round which will further minimize the energy consumption and increase network lifetime. Proposed protocol will save significant energy by reducing back transmission and sensing every points of the network in a stable manner. We have evaluated the proposed protocol and compared with LEACH-C and An Efficient Cluster Head Selection (ECHS). We have simulated our protocol and found major improvement of performance with respect to 1stNode Death (1ND), End Node Death (END) and consumption of energy vs rounds.
