Ad hoc device send packet requirement

[李若瑄]

Hello everyone,
I've run into a bit of trouble sending packets from A to B using ad hoc devices. As the email mentioned, 1) use the correct destination IP/Port, 2) a valid route 3) within the radio range can send the packet. However, it seems I've made a mistake somewhere along the line. Some nodes are unable to receive the packet, while others can without any issue.

I've already checked the relative distances using GetDistanceFrom() and examined the routing table with PrintRoutingTableAllAt(), but everything seems to be in order. I'm starting to wonder if I missed something or did something wrong.

In this image, node 3 and node 4 should be exchanging packets, but for some reason, they are not. Distance is in left part, routing table in the middle, and flow monitor in the right.

The attached file contains my code. Any suggestions or information would be appreciated.

Best regards!

Without the mobility trace I can't run exactly your script.

However, the routing table output is strange, and it looks like one I've seen in an old ns-3 version.

Mind checking if the problem persists with 3.41 or ns-3-dev ?

Hi, Tommaso.

Thanks for answering my question. I updated the version from 3.38 to 3.41. Routing table looks great now! However, a new issue appears : no packets are being received at any of the nodes.

The attached file is the missing tracing file and required data. Thank you for your support.

The nodes are too far away. We improved the models and now they're more strict on packet reception. Note that the actual one is the "correct" behavior, meaning that it more closely matches the one of real devices.

Got it. Thanks a lot for taking the time to answer my question, I really appreciate it.

Best regards!
