In order to reduce the energy consumption of cluster head in wireless sensor networks（ WSNs）clustering routing

a dual-cluster heads clustering routing algorithm based on cuckoo search（ CS） optimization is proposed. The CS algorithm construct fitness function by using residual energy of nodes and relationship of position between nodes and elects optimal dual-cluster heads. In which

the main cluster head fuse data and the vice cluster head sends the fused data to the base station. It relieves dual pressure of data fusion and transmission beared by single cluster head in the past

so that distribution of the overall energy consumption in each node is more balanced. Simulation experiment show that compared with LEACH algorithm

PSO optimization algorithm

CS algorithm has more advantages in reducing network energy consumption and prolonging network lifetime.
