In the heterogeneous wireless sensor networks, most algorithms assume that nodes are heterogeneous in terms of their initial energy (we refer to as static energy heterogeneity). However, little research focuses on dynamic energy heterogeneity, which means that energy heterogeneity of nodes results from adding a percentage of the population of sensor nodes to the network when the operation of the network...
In order to minimize energy dissipation and maximize network lifetime, a new energy-efficient algorithm (LEACH-WM) based on weight and intra-cluster multi-hop mechanism is proposed in this paper. In the steady phase of LEACH-WM, a weight relay is elected in the cluster according to member nodes' residual energy and their distances away from the base station (BS).Cluster head sends aggregation data...
