| Abstract: | By analyzing the operating mechanism of cluster-head election algorithm based on LEACH Protocol and to overcome the limitation of the network node energy of wireless sensor, an improved algorithm is proposed in the paper that in the different phases of cluster-head election algorithm, the energy and average distance should be considered as referential factor. The simulation results show that the improved algorithm made up the consumed energy of the network node and effectively lengthened the lifecycle of the network. |
