Detailed Description
A simple Decider implementation which only checks for a received signal if the receiving power is above a certain value.
Note: This implementation is only meant to be as a quick and ugly Decider to demonstrate (and print) how the AnalogueModels affect the signal. You should not take it as template for a real Decider!

Member Function Documentation
| virtual ChannelState ThresholdDecider::getChannelState | ( | ) | [inline, 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 from Decider.

{
return ChannelState(false, 0);
}
| virtual simtime_t ThresholdDecider::handleChannelSenseRequest | ( | ChannelSenseRequest * | request | ) | [inline, 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.
