基于ORwgh的无线传感器网络定位算法在军事物流可视化中的应用研究

Research on the Application of Orwgh-based Wireless Sensor Network Algorithm in the Field of Military Logistics Visualization

针对无线传感器网络的定位技术应用于军事物流可视化建设当中存在着非视距传播误差定位的问题,在传统的残差加权算法的基础上,提出了对原有算法的改进算法,即优先残差加权算法。该算法避免了由于距离测量值组合穷举时会消耗大量能量的缺陷,从而大大延长无线传感器网络的生存期,提高了军事物流可视化的后勤保障能力。

There exists the problem of non-line-of-sight transmission error positioning when wireless sensor network-based positioning technology is applied in the field of military logistics visualization. Aimed at mitigating the problem, on the basis of traditional residual weighting algorithm, an optimized residual weighting algorithm（ORwgh） is put forward to improve the original algorithm. The optimized resid- ual weighting algorithm （0Rwgh） can avoid the deficiency of excessive energy exhaustion due to the combination infinity of distance measurement values so as to greatly prolong the life circle of wireless sensor network, contributing to the enhancement of the support capabilities of military logistics visualization.
