Transmission-Model
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)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~Logarithmic Attenuation Model~~~~~~~~~
In this model, the radio range is a circle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

PSO-matlab
标准PSO算法源代码（matlab）
不少网友需要PSO源代码，现将很早前的matlab代码贴上来。不过俺已经不搞学术很久了，现从事财政公务员工作，因此可能无法解答更多问题。(Standard PSO algorithm source code (matlab)
that many users need to PSO source code matlab code much earlier now Tieshanglai. But I have been a long time not to engage in academic, civil servants are engaged in financial work, and may not answer more questions.)

一束光通过一个透明圆柱体，圆柱后有一个屏幕，程序最终反映屏幕上的
图象随圆柱半径的变化而变化。其中光强分布是采用相干叠加原理，因为其中采
样点数目不足，所以光强分布的结果和真实的有一定差距。增加采样点数目和改
变采样点范围能够改善输出光强的结果逼真程度。(一束光through a transparent cylinder, a cylindrical post-screen process will ultimately reflect the on-screen image with the cylindrical radius change. Light intensity distribution of which is the principle of coherent superposition, because the insufficient number of sampling points, so light intensity distribution of the results and have some real gaps. Increase in the number of sampling points and to change the scope of sampling points can improve the outcome of the output light intensity the degree of realism.)
