摘要
为准确判断作物的需水情况,为精准灌溉提供科学依据,采用无线传感器技术。并首先针对新疆农业监控低成本、长时间以及大规模的特点,解决了其部署问题。给出了一种两层的WSN部署架构,底层节点完全覆盖保证监测的精确度,基于距离和转发通信量的非均匀簇头部署方案使节点能量均衡消耗。通过仿真并与leach、Leach-c协议的结果比较,该部署架构达到了稀疏、节能、网络能量均衡消耗、系统生命期长的目标。
In order to precisely determine the extent of the water deficit and thus to provide a scientific reference for precision irrigation,a particular design of farmland surface humidity monitoring system based on wireless sensor networks is introduced.According to the features of XinJiang agricultural environment,a two-layer deployment architecture is proposed to satisfy the need of low-cost,long lifetime and large scale in this paper at first.In architecture the bottom layer is deployed evenly to monitor the information of soil moisture precisely and the cluster head nodes is distributed unevenly based on the number of packet transmitted and the distance to sink to ensure the cluster heads energy consumed balancedly.By the simulation and comparing to the leach-c and leach,it shows that the aims of scarcely deployment,energy-saving,equilibrium of energy consume and prolonging the system lifecycle is achieved.
