I don't know if you're just talking about changing the distance, in
order to do it you just have to increase the transmitted power Pt_
and check the variable distCST_:
#To have 240m,using freespace
set opt(prop) Propagation/FreeSpace ;# radio-propagation model
Antenna/OmniAntenna set X_ 0
Antenna/OmniAntenna set Y_ 0
Antenna/OmniAntenna set Z_ 1.5
Antenna/OmniAntenna set Gt_ 1.0 ;#be aware the Gt_ and Gr_ are setted as the
Antenna/OmniAntenna set Gr_ 1.0 ;#fixed value 1.0
Phy/WirelessPhy set freq_ 2.4e9
Phy/WirelessPhy set L_ 1.0
Phy/WirelessPhy set Pt_ 1.838e-5 ;#power needed to have 240m of distance
Phy/WirelessPhy set RXThresh_ 3.16e-14
Phy/WirelessPhy set CSThresh_ 3.16e-14 ;#Sensivity=-105 dbm
Phy/WirelessPhy set CPThresh_ 10
output:highestAntennaZ_ = 1.5, distCST_ = 239.9
To increase distance higher than that increase Phy/WirelessPhy set Pt_ ,
distCST_ will go above 240m.
I don't know but the article "Simulate 802.11b Channel within NS2"
might be useful for you (you can search it on google).
