Dear Raj Vikram,

I suggest you to see attached files on subject.

Best regards

Mohamed-Mourad Lafifi Thank u sir for the response.

I have gone through these research paper. But how to proceed in Matlab for implementing it. is any functions related to toa in matlab??

TOA is not available in MATLAB !! You need to write the script . It is roughly the round -trip-time (for 2-way TOA)

Aparna Sathya Murthy Thank u for the response.

Can u tell How to proceed in script Any rough Idea about the parameters and functions.

Scriptwise, you need velocity and propagation time and then the product is TOA .

Dear Mr. Vikram,

please see my publication on RG:

Research Distributed Gradient Descent Localization in WSNs: Summing-U...

You will find Matlab codes on using TOA with GD localization. Let me know if you have further questions.

All the best.

Nuha A. S. Alwan Thanks a lot sir, I already gone through the paper and it helps me a lot.

thank u again sir...
