-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)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
