摘要
无线传感网络被越来越广泛地应用到农田智能灌溉系统中,但在实际应用中,无线信号的传输质量随着所处农田环境不同而不同。为了经济、合理、高效地部署无线传感节点网络,选取2.4 GHz工作频段的无线节点,对其接收信号强度及丢包率进行研究,明确其变化特征,给出合理的传输距离及天线架设高度,为无线传感网络的节点部署提供参考。
Wireless sensor networks have been applied to the However, in reality, the quality of wireless signal transmission deploy wireless sensor network node in an economic, reasonable farmland intelligent irrigation system more and more widely. changed with the farmland environment changes. In order to and efficiently in such condition, wireless nodes with 2.4 GHz frequency was selected and its strength of receiving signals and packet loss rate was studied to figure out the variation char- acteristics, and present reasonable transmission distance and height of the antenna erection to provide references for the wire- less sensor network node deployment.
