摘要:
针对无线传感网络误差累计效应导致定位精度降低的问题,提出了一种考虑锚节点几何形状对定位精度影响的优化定位误差控制方法。首先基于测量距离和边缘夹角构建了锚节点与定位精度的数值关系;接着,提出了一种几何权重度量误差的参量,并构建了基于几何权重实时调整目标节点提升为锚节点的权重因子,有效降低了误差传播的累计效应,提升了整个网络目标节点的定位精度。计算机仿真结果表明,文章所述方法在不同的测量误差情况下均保持了较高的定位精度,在实验环境中平均精度有了较大提升。
Abstract:
Aiming at the problem that the accumulative error effect of wireless sensor networks leads to the reduction of positioningaccuracy, an optimal positioning error control method considering the influence of anchor node geometry on positioning accuracy isproposed. Firstly, the numerical relationship between anchor node and positioning accuracy is constructed based on measuring distanceand edge angle. Then, a parameter of geometric weight measurement error is proposed, and the weight factor of real-time adjusting targetnode to anchor node based on geometric weight is constructed, which reduces the cumulative effect of error propagation and improvesthe positioning accuracy of the whole network target node effectively. The computer simulation results show that the proposed methodmaintains high positioning accuracy under different measurement errors, and the average accuracy has been greatly improved in theexperimental environment.
