In general, the objective modular network testbed in C++ is abbreviated as OMNeT++ and it is the component based simulation library that is written in C++ and deployed to simulate communication networks.
We have described the process of creating modules in OMNeT++ through the utilization of C++ base code and that is stored in the file extension.cc.
For your reference, we have highlighted the sample code for arp based communication module.
void ARP::initialize(int stage)
{
cSimpleModule::initialize(stage);
if (stage == INITSTAGE_LOCAL) {
retryTimeout = par(“retryTimeout”);
retryCount = par(“retryCount”);
cacheTimeout = par(“cacheTimeout”);
respondToProxyARP = par(“respondToProxyARP”);
netwOutGate = gate(“netwOut”);
// init statistics
numRequestsSent = numRepliesSent = 0;
numResolutions = numFailedResolutions = 0;
WATCH(numRequestsSent);
WATCH(numRepliesSent);
WATCH(numResolutions);
WATCH(numFailedResolutions);
WATCH_PTRMAP(arpCache);
}
else if (stage == INITSTAGE_NETWORK_LAYER_3) { // IP addresses should be available
ift = getModuleFromPar<IInterfaceTable>(par(“interfaceTableModule”), this);
rt = getModuleFromPar<IIPv4RoutingTable>(par(“routingTableModule”), this);
isUp = isNodeUp();
}
}
As a final point, the research scholars can reach us when you people have to know a lot about the OMNeT++.
