19.2 The OTcl interface

Since the energy model is a node attribute, it may be defined by the following node configuration APIs:

$ns_ node-config -energyModel $energymodel \
                 -rxPower $p_rx \
                 -txPower $p_tx \
                 -initialEnergy $initialenergy

Optional values for above configuration parameters of the energy model are given in the following table:

Attribute	optional values	default values
-energyModel	"EnergyModel"	none
-rxPower	receiving power in watts (e.g 0.3)	281.8mW
-txPower	transmitting power in watts (e.g 0.4)	281.8mW
-initialEnergy	energy in joules (e.g 0.1)	0.0
