无线传感器网络定位用到的无线传输模型
Regular Model, Logarithmic Attenuation Model, DOI Model, RIM Model
(Wireless sensor network localization using wireless transmission model, Regular Model, Logarithmic Attenuation Model, DOI Model, RIM Model
Achieve functional distance and transmission attenuation swap
~~~~~~~~~~~~~~~~~~~~~~Regular Model~~~~~~~~~~~~~~~
In this model, the radio range is a circle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ReceivedSignalStrength=SendingPower-PathLoss
e.g, RSS=Pt-Pl(d0)-10*η*log10(dist/d0)
Pt:transmit power
pl(d0):the pass loss for a reference distance of d0
ηis the path loss exponent
above parameters are saved in ../Parameters_Of_Models.mat
dist:distance between sender and receiver(m)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
typical value:Pt=0-4dBm(max),Pl(d0)=55dB(d0=1m),η(2~4)=4(indoor,outdoor)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

BP
说明： 通过分析交通流量时间序列的特点，引入BP神经网络进行短时交通流预测。首先，分析了短时交通流量预测的意义及研究背景；然后，介绍了BP神经网络的结构模型、学习规则以及BP算法的改进算法；最后，通过BP神经网络对短时交通流进行预测，并分析了在各种不同条件下的预测情况。(through the analysis of the characteristics of traffic flow time series, introduces BP neural network for short-term traffic flow prediction. First of all, it analyzes the significance of short-term traffic flow prediction and research background. And then, it has discussed the model and structure, the study rule and the improved algorithm of BP neural network. Finally, by BP neural network to forecast the short-term traffic flow, it analyzes under different conditions of the neural network prediction.)

利用matlab的gui设计的带有输入和输出功能的界面图形，实现等距线可视性很强，自己独立编写的数据和图形，学习非常值得,实现pca压缩图像，matlab语言(The interface graphics with input and output function designed by GUI of Matlab can realize the visibility of isometric line. The data and graphics compiled independently by oneself are worth learning. The realization of PCA compressed image and MATLAB language is very worthwhile.)
