How to enclose meaningful data into UDP packet in INET?

[Winters Wen]

Hi there.

I want add some meaningful data into UDP packet, then send it out via wireless, if there some available samples?

Hi Winters,

    take a look on the UDPBasicBurst that shows how to send packets through a UDPSocket. In such application, it is considered the use of cPackets. Nevertheless, you can create customized messages by extending from cPackets.

Hi Ivo

Thanks for your reply.ao

By extending cPackets, Can I bring data from external program (outside of OMNeT++) in UDP packet?

Winters,

   by "external program" what are you refering? A pipe, a local file etc or something similar?  On the other hand, if you are talking about send data to external interfaces the INET offers support to.

Hi Ivo

The 'external program' means a third party software, this software  sends out strings periodically.

I want enclosed these strings into UDP packets in OMNeT++. Is this possible?

Thank you very much.

Winters

Hi Winters,

    but 'how' it sends? Through a sockets? If so, take a look in the support to external interface on INET. If you are talking about a local program you can create a pipe in order to send data from the application to INET.

To enclose data into UDP packets you must create a packet that extends from cPacket. In such customized packet you may use a ByteArray object to enclose real bytes.

Hi Ivo,

So sorry to ask you question again.

I looked the support to external interface on INET, and want to run a external client example (examples\emulation\extclient). But I cannot understand the README file of this example totally.

"On your server, add a route to the host 10.1.1.1 and set the gateway to the IP address of the computer, on which the simulation is running."

What is the sever mena? How to add the route to the host?  Can you give me some instruction on how to run this example?

Appreciate very much!

Hi Winters, sorry for the long delay.

I have never make transmissions through external interface. Nevertheless, by reading that README it indicates that in such example the ExtClient will communicate with an external server. In order to allow the communication from the server to the ExtClient you must add a route (using route command) to the host 10.1.1.1 through the simulation host computer (setting this as the gateway of this route).

- On your server, add a route to the host 10.1.1.1 and set the gateway to the IP address of the computer, on which the simulation is running.

I hope I have helped you.

Best regards,

   Ivo

Hi all,

I'm new in inet , i want too to add some information du the udp packet and send it via wireless . what you advice me to use to do this.

thank you

You can use inheritance: https://omnetpp.org/doc/omnetpp/manual/#sec:msg-defs:inheritance
