Hi,
I want to calculate the value of received signal strength, so I need to know the position of Mobile Node and Access Point. And I found something interesting in the file mobile/propagation.cc
Xr += r->getAntenna()->getX();
Yr += r->getAntenna()->getY();
Zr += r->getAntenna()->getZ();
Xt += t->getAntenna()->getX();
Yt += t->getAntenna()->getY();
Zt += t->getAntenna()->getZ();
And I print out these values :
Xt 589.478206: Yt 489.478206,Zt 0.250000:Xr 589.478206,Yr 489.478206:Zr 0.250000
Xt 600.000000: Yt 500.000000,Zt 0.250000:Xr 600.000000,Yr 500.000000:Zr 0.250000
Xt 589.487894: Yt 489.487894,Zt 0.250000:Xr 589.487894,Yr 489.487894:Zr 0.250000
Xt 620.503211: Yt 520.503211,Zt 0.250000:Xr 620.503211,Yr 520.503211:Zr 0.250000
.....
To my surprise is that the values of Xt,Yt are variant which are supposed to be invariable because the AP is fixed. So, How to explain these codes? Is antenna position relative to node position?
Thanks very much
