| Abstract: | An improved LEACH for heterogeneous wireless sensor networks is proposed.Nodes are distributed in a sensing area that is divided into a number of same equilateral hexagons.Heterogeneous nodes act as the cluster heads and ordinary nodes act as those cluster sensors in all clusters.The structure of WSNs is a two-layer structure.The upper layer consists of all cluster heads and the lower layer consists of all ordinary sensors managed by their corresponding cluster heads.The cluster heads and the ordinary senso... |
