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
