| void MMac::recv | ( | Packet * | p | ) | [virtual] |
Abstract method which has to be filled with the ad-hoc operations that the module has to do to the packet received
| p | pointer to the packet will be received |

Here is the call graph for this function:
| int MMac::recvSyncClMsg | ( | ClMessage * | m | ) | [virtual] |
Cross-Layer messages synchronous interpreter. It has to be properly extended in order to interpret custom cross-layer messages used by this particular plug-in. This type of communication need to be directly answered in the message exchanged in order to be synchronous with the source.
| m | an instance of ClMessage that represent the message received and used for the answer |
Reimplemented from PlugIn.

| int MMac::command | ( | int | argc, | |

TCL command interpreter. It implements the following OTcl methods:
Moreover it inherits all the OTcl method of PlugIn
| argc | number of arguments in argv | |
| argv | array of strings which are the comand parameters (Note that argv[0] is the name of the object) |

Here is the call graph for this function:
| void MMac::Phy2MacEndTx | ( | const Packet * | p | ) | [protected, virtual] |
Handle the end-of-PHY-transmission event
This method is expected to be re- implemented by a class inheriting from MMac in order to perform the necessary MAC operations.
| p | pointer to the packet whose transmission has ended. Note that the Packet is not any more under control of the MAC at the time this event occurs, hence the 'const' declaration. |

| void MMac::Phy2MacStartRx | ( | const Packet * | p | ) | [protected, virtual] |
Handle the detected-start-of-PHY-reception event (e.g., PHY preamble successfully detected, so we expect to receive a new packet, possibly with errors)
This method is expected to be re- implemented by a class inheriting from MMac in order to perform the necessary MAC operations.
| p | pointer to the packet whose reception has begun. Note that the Packet is not yet under control of the MAC at the time this event occurs, hence the 'const' declaration. |

Handle the end-of-PHY-reception event

double MMac::mac2phy_delay_ [protected] |
Delay when sending packets from MAC to PHY. Remember that setting this to zero might give strange results due to the possible generation of simultaneous events and how these might be scheduled by the simulator. If you want to avoid this effect, set the value to a very small value if you want to simulate 'zero' delay.
