problem with UdpApp

[Elaheh V]

Dear all,
I am using UDPBasicApp. I try to send a packet from host1 to host3.
Host1 has registered the port in the UDP layer at first but other
hosts haven't.

** Event #1 T=0 Network.mobileHost1.udp (UDP, id=13), on
`UDP_C_BIND' (cMessage, id=117)
Binding socket: sockId=0 appGateIndex=0 userId=-1 localPort=100

when host3 gets the UdpPacket:

** Event #113 T=0.901268068587 Network.mobileHost3.udp (UDP, id=61),
on `UDPBasicAppData-0' (UDPPacket, id=212)
Packet UDPBasicAppData-0 received from network, dest port 100
No socket registered on port 100

In the omnetpp.ini, I just set the destination address of host1:

**.mobileHost1.udpApp[0].destAddresses = "mobileHost3"

Udp just register the port of the sender (the one which I set the
destAddresses for) and leave the others.
I don't know how to solve this problem.
Any help would be appreciated.

Thanks.

I have searched the group for similar problem but I couldn't find any
explicit solution.

thank you for your reply.
I have these settings for udp application in my omnetpp.ini file:

# application settings
**.numUdpApps = 1
**.udpAppType = "UDPBasicApp"
**.udpApp[0].localPort = 100
**.udpApp[0].destPort = 100
**.udpApp[0].messageLength = 1250 bytes
**.udpApp[0].messageFreq = 0.9s

**.mobileHost1.udpApp[0].destAddresses = "mobileHost3"

which configuration should I add to these?

hi

what is mobilehost?
did you have bindToPort(localPort) in mobilehost initialize?

The actual code of UDPBasicApp can not work like sink.

two alternatives, change in the receiver UDPBasicApp by UDPSink
or
modify in the UDPBasicApp.cc code this

if (destAddresses.empty())
return;

bindToPort(localPort);

for this

bindToPort(localPort);

if (destAddresses.empty())
return;

Is there a way to refer to source address of the host in udpBasicApp other than hooking? I'm not really familiar with the mechanism and I did not find any useful clear way on the internet that explains it in a good way...

thanks.

If you are speaking about the address of the sender, the information is in the controlInfo field

I found the answer to my question. The below fetches the host (node) index for you:

getParentModule()->getIndex()
