基于无线传感器网络的农用大棚数据采集

为了将无线传感器网络更好地应用于农业环境监测中,提出利用感知层簇头节点收集数据的一种方法,即让簇内的普通节点同时向簇头节点传送数据,从而对系统加以改进。通过OPNET软件对系统性能进行仿真,分析在相同的参数下网络趋于稳定的时间以及平均时延。仿真结果表明,相比于簇内的普通节点顺序向簇头节点传递数据,建立在新方法上的机制可以有效缩短系统趋于稳定的时间,并能明显降低系统平均时延。

Research on the data collection in greenhouse based on wireless sensor networks

In order to make the wireless sensor network better apply to agricultural environmental monitoring,the method of data collection of the cluster head node in Perception layer,which was the ordinary node transmitted data to cluster head nodes at the same time,is introduced.Thus the system could be improved.Through the OPNET software for performance simulation,the time of the system to stabilize and the average delay in the same parameters are analyzed.The simulation results show that the mechanism established in the new method could effectively shorten the time of the system to stabilize and could reduce the average delay,compared to in alphabetical order to transmit data to the cluster head node.
