A wireless sensor network consists of large number of sensor nodes limited by a small energy spread in a large geographical area. Many algorithm collect information from the network by using clustering. LEACH is the most famous and popular one from this algorithm to maintain the energy efficiency of sensor nodes. In this paper, the authors propose a new algorithm to choose the cluster head with the highest energy. They have collected all the nodes in the array and arranged them in descending order and then they select the best three nodes with the highest energy as a main cluster heads.
