Abstract: A critical issue for data gathering in wireless sensor networks (WSN) is the formation of energy hole near the static sink. Hence, to overcome this limitation, a novel method is employed wherein grid-based clustering along with dual cluster heads (a combination of primary and secondary cluster heads) is used to achieve enhanced energy balance in the network thereby extending network lifetime. The important contribution of the work is the ease of grid cell formation and selection of cluster heads by centralised cluster configuration by static sink. The simulations results show that the grid-based clustering (GBC) with dual cluster heads perform better than other clustering schemes for uniform and non-uniform node distribution in terms of network lifetime and energy dissipation.
