摘要
无线传感器网络(WSN)在智能农业发展中具有良好技术优势和广阔应用前景,作为连接外界应用系统的桥梁,网关在WSN中具有重要作用。针对传统网关设备主要基于平面路由组网方法,单一接收汇聚节点数据并进行转发的特点,本文基于分簇路由算法的思想,设计了一种能量自给且融合汇聚节点功能的网关,提高了网关数据传输效率和丢包率。针对稻田环境信息采集特点,设计了混合天线分簇组网方法,结合此网关和组网方法进行了稻田环境组网试验,试验结果表明:网络丢包率为3.8%,网关数据传输效率提高了300%,为大覆盖区域稻田的远程监测提供了一种可靠的解决方案。
Wireless sensor network （WSN） has unparalleled advantages and broad prospects in development of intelligent agriculture. As the bridge linking to external application system, gateway plays an important role in WSN. Different from the charactetistics of traditional gateway equipment that mainly based on the planar routing network method and singly receiving and forwarding the data of sink node, in this paper a gateway that possesses energy self-sufficiency and fusing sink node function was designed based on clustering routing algorithm, which can improve the efficiency of data transmission and packet loss rate. Meanwhile, for the characteristics of large planting area, long monitoring cycle and strong interference to wireless signal transmission in the process of paddy environmental information collection, a clustering network method based on hybrid antenna was designed, and the paddy networking test was conducted combining with the gateway and networking method. Test result shows that the network packet loss rate is less than 3.8%~ and the data transmission efficiency of gateway increased by 300%, This study could provide a reliable solution to the remote monitoring of large coverage area paddy.
