Detailed Description
The basic Decider class.
The Deciders tasks are: 1. decide which packets should be handed up to the MAC Layer (primary task) 2. decide whether the channel is busy/idle at a time point or during a time interval (channel sensing)
BasePhyLayer hands every receiving AirFrame several times to the "processSignal()"-function and is returned a time point when to do so again.

Member Function Documentation
| virtual void Decider::channelChanged | ( | int | newChannel | ) | [inline, virtual] |
Called by phy layer to indicate that the channel this radio currently listens to has changed.
Sub-classing deciders which support multiple channels should override this method to handle the effects of channel changes on ongoing receptions.
- Parameters:
-
newChannel The new channel the radio has changed to.
Reimplemented in Decider80211MultiChannel, and Decider802154Narrow.

{}
| ChannelState Decider::getChannelState | ( | ) | [virtual] |
A function that returns information about the channel state.
It is an alternative for the MACLayer in order to obtain information immediately (in contrast to sending a ChannelSenseRequest, i.e. sending a cMessage over the OMNeT-control-channel)
Reimplemented in BaseDecider, DeciderUWBIRED, SNRThresholdDecider, and ThresholdDecider.

}
| simtime_t Decider::handleChannelSenseRequest | ( | ChannelSenseRequest * | request | ) | [virtual] |
This function is called by the PhyLayer to hand over a ChannelSenseRequest.
The MACLayer is able to send a ChannelSenseRequest to the PhyLayer that calls this function with it and is returned a time point when to re-call this function with the specific ChannelSenseRequest.
The Decider puts the result (ChannelState) to the ChannelSenseRequest and "answers" by calling the "sendControlMsg"-function on the DeciderToPhyInterface, i.e. telling the PhyLayer to send it back.
Reimplemented in BaseDecider, DeciderUWBIRED, and ThresholdDecider.
