Hello Manish, My understanding is that the two parameters are not related.
Pt_ defines the amount of power transmitted from the antenna (Phy/WirelessPhy), and thus; it defines (together with the RXThresh_ parameter) the range of the mobile-node. And it is not used by the energy model. txpower defines how much power a mobile-node, as a whole, consumes when it is transmitting, and it is the one used by the energy model. For example; the PRO/Wireless 3945ABG card on my laptop can consume a maximum power of 1.8 Watt while transmitting and a maximum of 1.4 Watt while receiving. But the maximum transmitting power is 15 dBm ( ~ 31 mW) ! -- Waleed Tuffaha On Wed, Jan 21, 2009 at 7:07 AM, manish chaturvedi <msc....@gmail.com>wrote: > > Hi, > > I am trying to incorporate energy model in my NS2.33 simulation.
