when the a packet is created the field creationTime is set,

e2eDelay = simTime() - tmpPkt->getCreationTime();

is the time since the creation, due to that the packet is sent immediately after the creation this is the end to end delay

the second you can find in any basic statistic book

Asunto: [Omnetpp-l] Can you explain to me the meaning of this code

In inetmanet / src / wpan / applications / Ieee802154TestApp / Ieee802154TestApp.cc.

void Ieee802154TestApp::handleLowerMsg(cMessage* apMsg)
{
...
simtime_t e2eDelay;

Ieee802154AppPkt* tmpPkt = check_and_cast<Ieee802154AppPkt *>(apMsg);

e2eDelay = simTime() - tmpPkt->getCreationTime();
e2eDelayVec.record(SIMTIME_DBL(e2eDelay));
....
}

and

sumE2EDelay += e2eDelay;
meanE2EDelayVec.record(sumE2EDelay/numReceived);

I know this code to calculate delay by dont understand meaning of these, Can you explain to me?

thank you!
