一种基于压缩感知的农业WSN数据传输方法

Agricultural WSN data transmission method based on compressed sensing

为实现科学的农业生产,无线传感网络被应用在农业环境的监测中,网络中传感器节点通常分布区域广密度大,采集到的数据量极大。该文提出将压缩感知技术用于传感器节点进行数据采集与传输的方法,仿真结果显示,该方法能接近完美的重构信号,减小传输的数据量,节省传感器节点通信耗能。

To achieve scientific agricultural production, wireless sensor networks are used in monitoring agricultural environment, the network sensor nodes are usually distributed widely and high density, the amount of data collected is enormous. This paper presents compressed sensing method used in sensor nodes for data collection and transmission, and the simulation results show that this method can keep perfect reconstruction of the signal, reducing the amount of data transmitted, saving sensor node communication energy.
