一种分区管理的温室传感器网络数据传输技术

基于无线传感器网络能量受限的特点，结合温室的结构特征，从网络结构设计入手，提出一种将温室网络划分成多个子网实现分区管理的数据传输技术。移动汇聚节点部署在温室上方的轨道上，在移动过程中分时地与相应区域内的传感器节点构成星形网络进行数据传输。详细介绍了此方案的网络模型、通信机制，以及其中的重要参数。研究结果表明：此方法与LEACH相比可节省能耗30％以上。

Subarea-management data transmission scheme of greenhouse sensor networks

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.
