摘要
The implementation of energy balanced routing is an effective way to prolong the lifetime of wireless sensor networks （WSNs）. To balance energy consumption, fuzzy next-hop selecting strategy was designed： nodes of different gradients are fuzzily classified into relevant levels; each level has a chance to provide a node with maximum residual energy as the next-hop. Based on the above strategy and directed diffusion （DD）, fuzzy next-hop selection based energy balance （FNSEB） routing protocol was proposed. The simulation results showed that FNSEB utilized the limited energy more thoroughly and rationally, decreased the average energy consumption and prolonged the lifetime of WSNs.
