UDP broadcast in OMNET

[Chakkaphong St.]

Hello,

I have followed suggestions on how to do UDP broadcast in OMNET on this link http://groups.google.com/group/omnetpp/browse_thread/thread/4dc2feef3ce53f85/2435092169557472?q=broadcast&lnk=ol& . However, it still does not work even I put only 3 host one is brocast host (host[0]) and the other two (host[1], host[2]) as receivers. The below is my code, but I am not sure whether there is something wrong or not. Could you give me a hint? One more doubt is when I am runing this code, what is the value of *.host[0].udpApp[0].destAddresses I should set in .ini file? I cannot leave it either blank or "255.255.255.255". Thus, I set it to "host[1]". Consequently, host[0] only unicast UDP packet to host[1] only. Pakcets arriving to host[2] are considered as noise. Could anyone give me suggestions?

void UDPBasicApp::sendPacket()
{
    cPacket *payload = createPacket();
    IPvXAddress destAddr = IPAddress::ALLONES_ADDRESS;
    sendToUDP(payload, localPort, destAddr, destPort);
    numSent++;
}
void UDPAppBase::sendToUDP(cPacket *msg, int srcPort, const IPvXAddress& destAddr, int destPort)
{
    msg->setKind(UDP_C_DATA);
    UDPControlInfo *ctrl = new UDPControlInfo();
    ctrl->setSrcPort(srcPort);
    ctrl->setDestAddr(destAddr);
    ctrl->setDestPort(destPort);
    ctrl->setInterfaceId(101);
    msg->setControlInfo(ctrl);
    EV << "***tor*** Sending packet: ";
    printPacket(msg);
    send(msg, "udpOut");
}

I will really appreciate your help.

Regards,
Chakky

What framework are you using? the broadcast is avalaible in inetmanet but not in inet-farmework

dear, mr. Alfonso, i would like to simulating use veinslte framework, i will make vehicle simulation only by use lte network. what should i do to choose the suitable broadcast application to send messages to the vehicles as the UE?

thankyou very much.

[Alfonso Ariza Quintana]

I don't know how works veins LTE, but, if you want to implement an application that could broadcast messages, it should be UDP, with TCP it is impossible to send broadcast messages.

i've been using ipv4addrees allones and allmcast host but it doesnt work. server send message to ip 255.255.255.255 but the car cannt receive the broadcast message. please help me.

Include in the configuration this

**.forceBroadcast = true

In other case the IP module implements limited broadcast (it is not enough to set the address to the address broadcast, it is necessary also to include the ports that the broadcast must be emitted).

Hi!

Has the broadcast been implemented by now in the inet framework? Or is it still only available in the inetmanet?

Best Regards,

Bruno
