Abstract: Research the energy consumption of wireless sensor networks.The paper puts forward a dynamic topology energy efficient clustering incremental algorithm.The algorithm uses the introduction of the energy factor of low complexity cluster head selection method,with some nodes move dynamic network topology,on data transmission through multi-hop route selection information in order to reduce energy consumption of wireless sensor networks. The experimental results show that the proposed algorithm with respect to LEACH algorithm can effectively reduce the energy loss of the network nodes and in the network life cycle has been greatly improved.
