Detailed Description

The Packets Generator class.

This class simply generates packets (DevPkt) randomly. The time between each packet generation follows a ranom distribution (an exponential time here).

Constructor & Destructor Documentation

DevPktGen::DevPktGen (  SysSAloha *  _System, DevAP *  _theAP )

Contructor. Remember to clear variables for initialization in Initialize(). Do NOT initialize variables here unless they are constants. Definition at line 17 of file devPktGen.cpp. References the_SG_Probe. : DEDevice(_System), System(_System), theAP(_theAP), counter(0) { the_SG_Probe = 0; };

Member Function Documentation

void DevPktGen::Initialize (   )  [virtual]

Initialize function. Here is where the parameters are read and the real initialization takes place. Note (again) that this function can be called multiple times; hence, you must clear previous instances. Here is also where the first Self Event should be fired. From now on, this class will be self-clocked. The first packet can be generated here or later, as you want. Reimplemented from DEDevice. Definition at line 38 of file devPktGen.cpp. References counter, dtList, DevPkt::Initialize(), MsgInterarrTimeGen, DEDevice::newEvent(), ProbeSG::Observe_S(), System, the_SG_Probe, and theAP. Referenced by SysSAloha::Initialize(). { DETime MsgInterarrTime = get<DETimeParameter,DETime>(Param, "MsgInterarrTime", "Dev_Test_PktGen", ""); MsgInterarrTimeGen = ExponentialDETimeRndGen(MsgInterarrTime); if( the_SG_Probe ) delete( the_SG_Probe ); the_SG_Probe = new ProbeSG( "the_SG" ); list<DevPkt*>::iterator dtListIter; for( dtListIter=dtList.begin(); dtListIter!=dtList.end(); dtListIter++) delete (*dtListIter); dtList.clear(); DevPkt* newPkt = new DevPkt( System, this, theAP, counter++); the_SG_Probe->Observe_S(1); newPkt->Initialize(); dtList.push_back(newPkt); newEvent(new Ev_PktGen_Generation(this), MsgInterarrTimeGen.get()); }
