Abstract: Developing an energy-efficient clustering protocol is one of the major issues in wireless sensor networks. In order to reduce overall energy consumption of wireless sensor networks, prolong network lifetime, the shortcomings of LEACH algorithm are studied. The clustering algorithm is composed of two phases, the cluster building phase and stable data communication phase. In this paper, the cluster head selection of the algorithm is improved. According to the residual energy of sensor nodes, communication energy consumption of neighbour nodes and the distance between the nodes and the sink nodes, a hierarchical routing protocol based on optimal clustering head for wireless sensor networks is proposed. On condition that the residual energy of the node exceeds a certain threshold, the probability of being clustering head is affected by the nodes' network parameters. Simulation results show that the proposed algorithm can balance the energy consumption and prolong the network lifetime.
