Therefore，an energy consumption ratio-based node rotation （ECRNR）scheme has been proposed in this paper. The purpose of this scheme is to allocate more sensor nodes at the positions of high energy consumption in turns，that is to say，the relay information is shared by more than one sensor nodes to avoid early energy consumption. Simulation results show that the scheme has prolonged the lifetime of networks a lot compared with traditional schemes.
