摘　　要：温室中传感器节点的位置大多是工作人员进行定位。为了满足温室监测的需求,本文使用了一种改进的无线传感器网络定位技术,着重研究了温室中传感器节点布置后自适应定位的技术。实验结果表明,MDH算法提高了节点的定位覆盖率,降低了平均定位误差,且减少了计算开销。这种定位技术适合用于监测温室的环境。In the greenhouse, the localization of sensor nodes is mostly positioned by the worker. In order to meet the demand of the greenhouse monitoring, it is focused on the self-adaptation positioning technology of sensors in the greenhouse. An improved node positioning technology is proposed in wireless sensor network. The experiment resuhs show, the average positioning error is reduced, and the node location coverage rate is improved. The positioning technology is applied to the greenhouse monitoring system.
