[ns] What's the relationship of Pt_ and Pt_consume_

[Daniel Dekst]

Hi, all
   
  What's the relationship of Pt_ and Pt_consume_? 
   
  I know when a node receive a packet, it will calculate Pr according to Pt_, 
then decide whether successfully capture this packet. If I calculate "txPower" 
according to the distance between two nodes, and replace the Pt_ then the 
transmission range will be changed. But how much energy should be decreased 
also should be changed, which is implemented in function 
"em()->DecrTxEnergy(actual_txtime, Pt_consume_)".
   
  Then should we use "(txPower/Pt_)*Pt_consume_" to replace "Pt_consume_" or 
some other functon?
   
  Thanks in advance,
  Pei
