New clustering scheme for wireless sensor networks

A challenging issue in wireless sensor networks (WSNs) is the energy saving to extend the networks lifetime. In this paper, we propose a novel Energy-Aware Clustering algorithm (EAC) for prolong the wireless sensor network lifetime, EAC achieves a good performance in terms of lifetime by balancing the energy load among all the sensor nodes in the network. EAC introduces the energy factor for cluster head selection and distance factor for non-cluster heads to select its cluster head. Simulation results show that the proposed algorithm increases the network lifetime in compare of the well-known LEACH protocol.
