基于周立功USBCAN模块通信的上位机应用软件(CANTest communication module)

在TOA测距的基础上，提出了一种三维无线传感器网络节点定位算法，并对其性能进行了分析，给出了算法的时间同步误差和定位误差。最后在现有仿真平台OMNET++的基础上构建三维仿真模块，对算法进行了仿真实现，给出了该算法的定位精度和覆盖率(This paper proposes one three-dimensional localization algorithm based on TOA distance measurement and analyzed the performance of the algorithm calculated time synchronization error and localization error. Finally it constructed three-dimensional simulation modules based on OMNET++ and implemented the algorithm educed the localization precision and coverage.)
