I am new to Omnetpp, and I am trying to send messages from one node to another wirelessly. Basically, I would like to do something as in the tictoc example of Omnetpp (https://docs.omnetpp.org/tutorials/tictoc/) but then wirelessly. I have installed INET already, and I have seen the wireless example, which uses the UdpBasicAPP. However, I do not know how to change the data of the message send while using the UdPBasicAPP. In my case, what I am sending (i.e. the data) is very important because it is part of a bigger project. Eventually, the idea is to use the 802.11p standard (which exists in VEINS) and multiple nodes, but I thought this was a good place to start.

I hope someone can help me out.

Kind regards

  1. just to be aware: 802.11p is also supported directly in INET. Just set the opMode parameter on the network interface.
  2. You will need to create your own application module. Take a look/copy UdpBasicApp and modify it according to your needs. Check the sendPacket() function which creates an ApplicationPacket. ApplicationPacket contains only a single sequence number, but you can create your own application level data structure and use that for sending.

  • Okey I figured out how to do it. The code and the explanation can be found on github: https://github.com/Jamie-Wubben/omnetWireless – jamie wubben Jun 29 '22 at 11:11
