Regarding on how to optimize and improve the energy efficiency of nodes, here presents a clustering protocol based on PSO and has a balanced perception of distance and energy of the double cluster head centralized network. It mainly improves the original particle swarm optimization by optimising the fitness function. In addition, this algorithm Data transfer phase in the primary division of labor from the cluster heads to extend the cluster head reelection cycle, and the simulation results show

... that the algorithm in a balanced energy consumption across the network while extending the life cycle of the entire network.
