Hello,All, I want to calculate the signal strength received from two access points in free space. And I find there is a function called double FreeSpace::Pr(PacketStamp *t, PacketStamp *r, WirelessPhy *ifp) {...}[ns-2.31/mobile/propagation.cc] But, I don't know how to call this function to calculate the value of SS, so, could you do me a favor? Actually I don't know if this function works or not? if not, is there any way ? Thanks. Leyond
