pcap recording #140

Closed vonmuenchow closed 3 years ago

vonmuenchow commented 3 years ago

Hi, I have a simple scenario with a single RSU und several vehicles sending out CAMs. At the moment I record the station ID and vehicle speed as vectors in a .vec-file, which works fine. But the first problem with this is, that I can't assign the speed to a specific vehicle anymore. Secondly I can't record the path history stored in the CAM (or at least I don't know how to do this).

What I would like to do instead is to record all CAMs received from the RSU and store these messages in a seperate file for later analysis. As far as I understand, INET is capable of recording messages as pcap-files, which would be perfect for my use-case. To do so I added the following lines in my config but no recorder shows up in Omnet++

*.rsu[*].numPcapRecorders = 1
*.rsu[*].pcapRecorder[*].pcapLinkType = 105 # 802.11
*.rsu[*].pcapRecorder[*].pcapFile = "results/rsu.pcap"

So my questions are:

  1. Is it (at the moment) possible to record received CAMs in pcap format with Artery?
  2. If the answer is yes: What do I have to consider? Or what am I doing wrong right now?
  3. If the answer is no: What would be the best way to extract and store station ID, speed, position and path history as a tuple? BTW: The RSU is just a data sink (so I could replace it with something else that can receive CAMs).

Best reguards Max

Note: In generel I'm new to artery and network simulation. So I'm figuring out how everything works and how to get use out of it. And if it matters: I'm using Artery via the provided virtual machine.

I just found the solution in issue #105!

@vonmuenchow could you please elaborate on how you were able to use the INET pcap recorder to record the messages from Artery?
