Abstract: Because of the influence of energy consumption of wireless sensor network, the location information of nodes in wireless sensor networks is very important, the current general localization algorithm is not suitable for harsh environment. This paper proposes a scheme based on the ranging node localization to improve the overall performance of the network. The routing algorithm is designed to directly affect the energy consumption of the system, in order to prolong the network lifetime, an improved LEACH routing algorithm was proposed. In the cluster head selection phase, using the residual energy of cluster head node selection mechanism to avoid low residual energy node to be cluster head, then the data transfer phase, using single-hop and multi-hop hybrid transmission mode, to balance the whole network energy and prolong the life of the entire network.

 

Keywords: Wireless sensor network, Positioning design, Energy-efficient, Cluster head selection, Routing algorithm.
