Abstract :The WSN is a network that performs communication by dividing the network into sub-divisions named as clusters. The clusters are made up of group of sensor nodes. A node is elected from each and every cluster that represents that corresponding cluster. The cluster head selection is one of the major tasks that can affect the whole performance of the network. The most of the cluster head selection techniques choose the CHs on the basis of link cost function that evaluates only the distance of the candidate node with rest of the adjacent node, other factors such as energy of the candidate node, distance of the candidate node to the sink node were ignored.This study presents a new mechanism for CH selection i.e. E-DECH (Enhanced-DECH). The improvements are introduced in the terms of parameters that are evaluated to measure the minimum link cost function. The proposed work evaluates the link cost function on the basis of distance of the candidate node from adjacent nodes as well as sink node also. The amount of residual energy is also considered as a major aspect for evaluating the link cost function. The results portrays the contrast among DSBCA-DECH and E-DECH in the terms of number of dead nodes, number of alive nodes and existence of first dead node in the network.
