I'm working on ns-2.35, and I want to simulate wireless-hart in ns2.
I got a code from an author, and i followed his procedure to integrate the wireless-hart simulator in ns2, but when i run any WPAN example i got this message:

num node is 46
cannot open request log.




my OS is Ubuntu 16.04, 64-bit

I will be thankful for you if any one help me.

Since you got 'a code from an author', why don't you contact that person and ask THEM??? You don't tell us/show us what this code is...and we can't guess. Best thing would be to look at the log file name and path, and make sure your user can write to that directory/file.

hey Sir plz u can help to implement wirelesshart using ns2

You need to read the LQ Rules and the "Question Guidelines". Don't use text speak (it's "you" not "u", "please" not "plz", etc.), don't hijack someone elses thread with your own question, and don't re-open old threads unless you're going to contribute to the answers in that thread. Also, you need to do basic research before posting a question.

As we told the original poster of this question, tell us what you've done/tried first. Did you look up anything about NS2 and wireless-hart? Follow any of the guides? What version/distro of Linux are you using?? Without details, we can't help.

thank you Sir ,

you can help me to implement wirelesshart it is a standard like bluetooth but it in industrial domain using NS2

Again, as you were told before:

• DO RESEARCH ON YOUR OWN FIRST. You can look up steps, guides, etc., because there are resources you can find on your own, and we are not going to look them up for you.
• OPEN YOUR OWN THREAD FOR YOUR OWN QUESTION. That means, do not reply in this thread, but open a NEW thread.

Open a new thread only AFTER you have done your research and are actually stuck. We are not going to look up guides for you, type up how-to documents, etc. And if you wind up posting a question, you will, AGAIN, have to provide details, like version/distro of Linux, version of NS2, what guide(s) you followed, etc.
