Based on the energy-constrained feature of wireless sensor networks

combined with the structural characteristics of the greenhouse

starting from the network architecture

a subarea-management data transmission scheme of greenhouse wireless networks is proposed.The mobile sink nodes are deployed on the top of the greenhouse

during its constant movement

networking star-network with correspond nodes at the bottom of the greenhouse during different time slot.The network model

communication mechanism of this scheme are introduced in detail

and the key parameters are analyzed.The simulation results verify this sheme can reduce energy comsumption above 30 % compared to LEACH.
