Detailed Description

A WiFi radio energy model.

4 states are defined for the radio: TX, RX, IDLE, SLEEP. Default state is IDLE. The different types of transactions that are defined are:

Tx: State goes from IDLE to TX, radio is in TX state for TX_duration, then state goes from TX to IDLE.
Rx: State goes from IDLE to RX, radio is in RX state for RX_duration, then state goes from RX to IDLE.
Go_to_Sleep: State goes from IDLE to SLEEP.
End_of_Sleep: State goes from SLEEP to IDLE. The class keeps track of what state the radio is currently in.

Energy calculation: For each transaction, this model notifies EnergySource object. The EnergySource object will query this model for the total current. Then the EnergySource object uses the total current to calculate energy.

Default values for power consumption are based on measurements reported in:

Daniel Halperin, Ben Greenstein, Anmol Sheth, David Wetherall, "Demystifying 802.11n power consumption", Proceedings of HotPower'10

Power consumption in Watts (single antenna):

$P_{tx} = 1.14$ (transmit at 0dBm)

$P_{rx} = 0.94$

$P_{idle} = 0.82$

$P_{sleep} = 0.10$

Hence, considering the default supply voltage of 3.0 V for the basic energy source, the default current values in Ampere are:

$I_{tx} = 0.380$

$I_{rx} = 0.313$

$I_{idle} = 0.273$

$I_{sleep} = 0.033$

The dependence of the power consumption in transmission mode on the nominal transmit power can also be achieved through a wifi TX current model.

◆ DoDispose()

void ns3::WifiRadioEnergyModel::DoDispose ( void )

overrideprivatevirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.
