摘要
针对现有基于对数正态信道模型的定位方法在各向异性环境下定位精度不理想的问题,提出一种具有环境自适应能力的移动节点定位模型,在传统信道模型中引入障碍物建模参数,通过新的模型表达解决无线网络各向异性环境中的节点定位问题。实验结果表明,该模型有良好的定位能力,对环境中的障碍物和其它干扰具有较低的敏感度。
To address the problem that existing lognormal channel models are too simplistic to a real field situation,an environment adaptive localization model was proposed which could deal with the problem of random obstacles by introducing additional terms.A novel model was designed for nodes localization in anisotropy networks.Experimental results reveal the proposed localization model has ideal precision and it is not sensitive to walls and other obstacles.
