Aiming at the low energy adaptive clustering hierarchy algorithm has the problem that cluster head dis_tributes unreasonably and energy consumption inequality in the network, an improved low energy adaptive clustering hierarchy algorithm based on particle swarm optimization algorithm is proposed in this paper. Firstly, the problem of selecting split line are tuned into nonlinear constraint optimization problem, and the particle swarm optimization algo_rithm is used to solve the problem n which defect of particle swarm optimization algorithm are solved,finally, the simu_lation experiments are carried out to test the performance of algorithm. The results show that the proposed algorithm can effectively improve the network energy efficiency and achieve energy consumption balanced among nodes, so it can pro_long life time of wireless sensor network compared other improved low energy adaptive clustering hierarchy algorithm.
