Low energy consumption and increasing the network lifetime are key factors in proposing a wireless sensor network protocol. Clustering or hierarchical methods have been proven to be effective in decreasing the energy consumption. Clustering methods make use of cluster-heads in order to achieve the efficiency in wireless sensor networks. Gridding approach is used in clustering that divides the network layout into grid with nodes falling into the each grid. Cluster-head provides a hierarchy in the network, one between the nodes and cluster-head and second between the cluster-head and the base station. Cluster-heads aims at aggregating the data from sensor nodes and decrease the controlling data in the network.
