Abstract Based on the strict energy limitations in wireless sensor network, how to decide the number of clusters, which is influenced with the total number of sensors and the characteristics of the disposed area, is the key idea in clustering algorithm. The energy model used in the communication process is given, the optimization of the number of clusters according to different level of clusters is analyzed theoretically. The simulation results show that the rational number of clusters can unify the energy distributions of sensors and improve the lifetime of network.
