Member Function Documentation

cMessage * BasicMacLayer::decapsMsg (  MacPkt *  msg  )  [protected, virtual]

decapsulate the network message from the MacPkt Decapsulates the network packet from the received MacPkt

MacPkt * BasicMacLayer::encapsMsg (  cMessage *  msg  )  [protected, virtual]

Encapsulate the NetwPkt into an MacPkt. Encapsulates the received NetwPkt into a MacPkt and set all needed header fields.

void BasicMacLayer::handleLowerMsg (  cMessage *  msg  )  [virtual]

If message arrives from lower layer, check whether it is for us. Send it up if yes. Implements BasicLayer. Reimplemented in CSMAMacLayer.

virtual void BasicMacLayer::handleUpperMsg (  cMessage *  msg  )  [pure virtual]

Handle messages comming from the network layer. Here is the place to implement a real medium access functionality. If message arrives from upper layer, make a MAC packet from it (encapsMsg) and send it down (sendDOwn). See also: encapsMsg, sendDown Implements BasicLayer. Implemented in AlohaMacLayer, and CSMAMacLayer.

void BasicMacLayer::initialize (  int  stage  )  [virtual]

Initialization of the module and some variables. First we have to initialize the module from which we derived ours, in this case BasicLayer. Reimplemented from BasicLayer. Reimplemented in AlohaMacLayer, and CSMAMacLayer.
