摘要
【目的】提出一种基于无线传感器网络的温室环境监测系统低功耗协议,使利用无线传感器网络来进行温室环境监测更节能。【方法】以温室环境监测系统为背景,提出一种改进后的低功耗LEACH协议,并利用NS2仿真软件对改进后的协议进行仿真验证及分析。【结果】改进后的协议能够通过简化簇头选择的过程和加入数据融合模型来节约能量,减缓节点死亡的速度,延长网络的生命周期。【结论】改进后的协议(NewDA)比LEACH协议更适合在温室监测系统中使用。
[Objective]This research put forward a type of low power consumption protocol in greenhouse environ- ment monitoring system based on wireless sensor network in order to make use of wireless sensor network to save more en- ergy in greenhouse environment monitoring. [Method ]By using the greenhouse environment monitoring system as back- ground, an improved low power LEACH protocol was put forward and was validated and analyzed through the use of NS2 simulation software. [Result]The improved protocol saved energy, slowed down the node death rate, and prolonged the network life cycle by simplifying the cluster head selection process and data fusion model. [Conclusion]The improved pro- tocol (New DA) was more suitable for greenhouse monitoring system usage than the LEACH protocol.
