The paper puts forward an improved algorithm of the LEACH in wireless sensor network to effectively balance energy of nodes.Cluster heads are selected if the distance between cluster heads is greater than a certain threshold,since the cluster heads are distributed evenly in the monitoring area.Then a comparison is made of the improved algorithm of the LEACH with the LEACH in the aspect of energy consumption.Simulation results show that the improved algorithm of the LEACH is superior in balancing energy of nodes and extending the network life.
