本文件用于演示无线传感器网络中的两个经典算法所编写的，关于无线传感器网络自身定位系统算法中的凸规划定位算法和DV-coordinate算法的演示。(This file is used to demonstrate wireless sensor networks written two classical algorithms, convex programming algorithm and DV-coordinate positioning algorithm demo on their own positioning system for wireless sensor network algorithms.)

质量导向算法是一种非常有效的相位解包裹算法，属于路径跟踪算法。质量导向算法的基本思想是用一幅质量图来引导相位展开，这个质量图可以用来描述包裹相位图中每个像素质量的好坏。(Quality oriented algorithm is a very effective phase unwrapping algorithm, which belongs to path tracking algorithm. The basic idea of the quality guided algorithm is to use a quality map to guide the phase unwrapping, which can be used to describe the quality of each pixel in the wrapped phase map.)

基于MATLAB利用Particle-in-cell模型,对梯形管内壁等离子体离子注入过程,进行了二维数值模拟.计算结果表明在中心电极附近出现了“阳极鞘层”,该鞘层内部不存在离子,而且在鞘层边缘离子密度最高.在上下管壁上的离子注入剂量呈现“m”形分布.通过对注入过程中等离子体密度分布和不同时间段管壁不同位置离子注入剂量的跟踪,发现“阳极鞘层”扩展行为是导致“m”形分布的原因.由于梯形管形状的不对称性,“阳极鞘层”的边缘向梯形长底方向扩展较快.在注入初始时刻离子注入的能量很低,随着时间延长离子能量逐渐升高,这是由离子初始位置决定的.可见梯形管自身形状决定了鞘层形状和最终的离子注入能量和剂量分布.(Based on MATLAB use Particle-in-cell model, the trapezoidal pipe wall plasma ion implantation process, the numerical simulation of two-dimensional calculation results show that in the vicinity of the center electrode to a "anode sheath," which does not exist inside the plasma sheath, and the highest in the sheath edge ion density ion implantation dose showing the upper and lower walls of the "m"-shaped distribution through the process of injecting the plasma density distribution and the wall at different locations in different time periods ion implantation dose tracking, found that "anode sheath "extension behavior is leading to" m "-shaped distribution of the reasons due to the asymmetry of the trapezoidal shape of the tube," Edge anode sheath "extension to the end of a long trapezoid direction quickly in the initial moment of implantation energy ion implantation is low ion energy with time gradually increased, which is determined by the initial position of the ion. visible trapezoida)
