Detailed Description

A WiFi radio energy model.

Doxygen introspection did not find any typical Config paths.

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

1. Tx: State goes from IDLE to TX, radio is in TX state for TX_duration, then state goes from TX to IDLE.
2. Rx: State goes from IDLE to RX, radio is in RX state for RX_duration, then state goes from RX to IDLE.
3. Go_to_Sleep: State goes from IDLE to SLEEP.
4. 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 CC2420 radio chip, with supply voltage as 2.5V and currents as 17.4 mA (TX), 18.8 mA (RX), 20 uA (sleep) and 426 uA (idle).

void ns3::WifiRadioEnergyModel::DoDispose ( void  )

privatevirtual

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

Subclasses are expected to implement their real destruction code in an overriden 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.

Reimplemented from ns3::Object.
