Hello,(adsbygoogle = window.adsbygoogle || []).push({});

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 :

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.
