Hello everyone, I went across so many materials for finding out how to put the right transmission power in "Phy/WirelessPhyExt set Pt_", but unfortunately couldn't get it right, so far!
The new module 802.11Ext has a number of parameters added up to make things more accurate. Initially in the older module of 802.11, things where controlled with RXTresh_, but this is not the case with 802.11Ext. I want to make a transmission to a distance (d) = 300 m, where i ll be using different propagation models, such as FreeSpace, TwoRayGround and Nakagami. I ll be using the parameters, given below (URL below), but can't really figure out how to adjust Pt_ for any desired distance that i want, e.g. d=300. https://sites.google.com/site/nahoons2/english-con/ns2-simulation-with-802-11p Any help would be really appreciated...Thanks in advance.
