I hope everyone will be fine.

My question is how I simulate vanet in which RSUs communicate via LTE and vehicle to vehicle or vehicle to rsu, they communicate via DSRC.

Why do we use the Nakagami Propagation model instead of the Two-Ray model in LTE

$ cd lte-ex_12.17/

$ grep -Rin Nakagami *

$ grep -Rin TwoRayGround *

Nakagami is used in Mac 802.11p examples.

TwoRayGround is used in Mac 802.11 examples,

kindly where can I found this file "Wave-DSRC-LTE file.tcl" 

[knudfl]

engi ....

"file.tcl" means any relevant simulation example.

DSRC-ex-2.tar.gz

..... I guess you can add LTE settings to the DSRC example ........

Dear Kund Larsen,

Thanks for your response 

kindly, 

-would you please share 4G/5G tcl codes? 

-Would you please share IoT, vehicles, or wireless sensors? 

-Some LTE tcl during execution showed " Segmentation fault (core dumped)?

Yours Sincerely, 

Ihab

Segmentation fault : ns-2.35 was issued year 2011, and many files are older.

Please do not expect all simulations to work any more.

Older OS' may be OK with the simulations, e.g. Ubuntu 16.04.

And some simulation are working better with ns-2.33

grateful for the precious response

Dear Kund, 

Your response is really helpful. Would you please help with how to add the LTE setting to the DSRC example?

Dear Kund, 

I've installed ns-2.33, where I paid attention to editing all relevant files.

Nam is not working as attached below :

NAM is a separate application, so any valid 'nam' binary can be used. (The Ubuntu nam package is usually corrupt.)

Please install a valid package = nam_1.14_amd64.deb
