面向智慧农业的无线传感器路由协议和节点定位算法研究

随着人类社会的的进步，物联网技术，云计算，区块链，大数据等先进的技术给人类社会的各个方面带来了翻天复地的改变，为了实现农业生产状态的智慧化，无人化管理，基于无线传感器网络技术的农业无线监控系统研究将从无线监控系统的路由协议算法和节点定位算法两方面进行探讨研究。在路由协议算法方面提出了基于划分四边形网格分簇的拓扑控制算法，并从网络拓扑结构，节点死亡、能量消耗三方面和LEACH算法进行对比，从仿真结果可以看出，基于划分四边形网络分簇的算法比LEACH算法性能更优。节点定位算法方面提出基于临时锚节点逐步定位算法，对节点定位算法从不同节点的邻居节点图和节点误差两方面做对比，仿真对比的结果表明农田面积为1000m*1000m，锚节点为50，传感器的数量为200时，网络连通性最大，节点定位误差最小，构建的无线监控系统适合于农田，温室大棚等农业应用。

Research on wireless sensor routing protocol and node location algorithm for intelligent agriculture

With the progress of human society, the Internet of things technology, cloud computing, chain blocks, big data and other advanced technology to all aspects of the human society has brought a proud forte changes, in order to realize the wisdom of the agricultural production status, unmanned management, agricultural wireless monitoring system based on wireless sensor network technology research will be from the routing protocol of wireless monitoring system algorithm and the node localization algorithm two aspects carries on the discussion.In the aspect of routing protocol algorithm, a topology control algorithm based on quadrilateral grid clustering is proposed, and the network topology, node death and energy consumption are compared with the LEACH algorithm. From the simulation results, it can be seen that the algorithm based on quadrilateral network clustering has better performance than the LEACH algorithm.Temporary anchor node localization algorithm based on node localization algorithm, step by step from different node to node localization algorithm of neighbor nodes and node error comparing two aspects, the results of the comparison of simulation indicate that farmland area is 1000 m * 1000 m, the anchor nodes to 50, the number of sensors is 200, network connectivity, the largest node positioning error minimum, build a wireless monitoring system for farmland, greenhouses and agricultural USES.
