The emergence of wireless sensor networks (WSNs) increasingly attracts many researchers. A big challenging issue in the WSN is to replace the sensor nodes when they run out of energy. Hence, it is indispensable to design a cluster-based routing for WSN so as to prolong the lifetime of a network. In this study, a clustered routing approach is proposed to attain energy efficiency by applying gravitational search algorithm (GSA). GSA has been used for assigning sensor nodes to an appropriate cluster head (CH) in a load-balanced way such that it reduces the energy consumption and hence enhances the lifetime of a network. The proposed approach outperforms popular clustering approaches, such as LEACHC, DEEC, (ACH)2, HCCRFD, and GSA-EC, relating to various performance parameters, such as network lifetime, energy dissipation and the number of packets sent to base station.
