Design and implementation of gateway for hybrid antenna clustering routing algorithm in paddy monitoring

摘要

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 characteristics 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.
