GPSR does not work properly when using 2 source nodes send simultaneously

[maicuongtho]

If I just use only one U1, or U2 it works OK, (test on StationaryMobility config)

for the case only one source node U1 send to GCS

Thanks for reporting this issue. I need the exact NED files and INI file (including the * charaters), please edit the post.

[maicuongtho]

Thanks for help. Github editor reject some special character, so i attach my full simulation folder (which include .ini and .ned file). MoPhongGPSR.zip

You can quote file contents on GitHub.

Anyway, the zip file you sent contains a different scenario than the one on your screenshot. I started the StationaryMobility config and for me both U1 and U2 can send traffic to GCS. I cannot reproduce your issue.

I have edited the original post to include proper code block. FYI, use ``` (three back quites) to delimit a code block, both at the start and at the end. (or just select your code block and use the code toolbar button. github will do the rest.
