Hello, I want to calculate sensor transmission and reception energy per cycle from RF transmitter data sheet. I need these values to set my energy model parameters in NS2 simulations. To make clear, in NS2 simulations we set our energy model such as below : -energyModel EnergyModel \ -idlePower .45 \ -rxPower .5 \ -txPower .5 \ -sleepPower 0.005 \ -initialEnergy 1000 ..... Therefore I need to find and calculate transmission and reception power of my selected RF transmitter from its data sheet. I want to use this RF transmitter data sheet : http://www.rfm.com/products/data/wsn802gc.pdf [Broken] According to data sheet the RF Transmit Power is 10mW. So I guess the calculated numbers should be in mW. The problem is that for example by multiply Transmit Mode Current with Power Supply Voltage the expected values are not result ... I will be glad if anyone can explain the method for calculating the mentioned parameters(txPower,rxPower,..) from the data sheet.
