Research of Probability Distribution of Centroid and DV-Hop Algorithm

为了对质心定位算法和DV-Hop定位算法的概率分布特征进行研究,在深入研究质心定位算法和DV-Hop定位算法的基础上,提出了一种概率分布特征的分析算法,并在MATLAB平台上进行了仿真实验。实验结果表明,在相同的节点分布密度以及网络连通度的条件下,在锚节点数量较少情况下,DV-Hop定位算法比质心定位算法落在规定范围内概率大,在锚节点数量上升到一定数量后,质心定位算法将接近并超过DV-Hop定位算法的概率分布。

To study probability distribution of centroid and DV-Hop algorithm,An algorithm on probability distribution of centroid and DV-Hop is proposed.It is simulated in MATLAB.The experimental results show that,the connectivity conditions in the same node density and network,the number of anchor nodes are low,DV-Hop algorithm is better,to the rise in the number of anchor nodes number,DV-Hop algorithm is better.
