基于压缩感知的无线传感器网络节点定位系统设计

Design of Node Location System for Wireless Sensor Networks Based on Compressed Sensing

由于传统的无线传感器网络节点定位系统,在无线传感器网络节点定位时平均定位误差大,因此无法实现节点精准定位。为此,笔者设计了基于压缩感知的无线传感器网络节点定位系统。该系统选用型号为OPO7004845259的压缩感知无线传感器,通过MCI-154841623核心控制芯片提高无线传感器网络节点的定位感知能力,通过数据库查询定位获取压缩感知定位点坐标。仿真结果表明,设计的定位系统平均定位误差最低为0.95 m,远低于实验对照定位系统的平均定位误差,定位能力更强,可以对无线传感器网络节点进行精准定位。

Due to the traditional wireless sensor network node positioning system,the average positioning error of wireless sensor network nodes is large,so it can not achieve accurate positioning.For this reason,a wireless sensor network node location system based on compressed sensing is designed.The system selects the model of opo7004845259 compressed sensing wireless sensor,improves the location sensing ability of wireless sensor network nodes through mci-154841623 core control chip,and obtains the coordinates of compressed sensing location points through database query and location.The simulation results show that the average positioning error of the designed positioning system is at least 0.95 m,which is far lower than the average positioning error of the experimental control positioning system.The positioning ability is stronger,and it can accurately locate the wireless sensor network nodes.
