Because wireless sensor network nodes have limited energy and cannot be charged,this paper proposes an energy-balanced nonuniform clustering scheduling algorithm(EBNC_CHES)to extend their network life.On the basis of the sparrow search algorithm,a time competition mechanism is introduced to EBNC_CHES to reduce redundant information acquisition and energy transmission.At the same time,it adopts K-means nonuniform cluste-ring to balance the network energy consumption between clusters and introduces improved sparrow search to balance the energy consumption within clusters in cluster head election.Compared with LEACH,EECHS_ISSADE,and EESSTBRP,The simulation results show that this algorithm reduces redundant information by 81%,80%,and 55%,improves energy utilization by 133%,50%,and 11.4%,and extends life by 52.8%,43.5%,and 12.2%,respectively.
