Simple CSMA/CA protocol for NS3

[Junseok Kim]

Hi All,

I know, somebody already posted simple wireless module but I'm
introducing another simple wireless module.
I finished this module 1yr ago but publish today.. cause you know..
the phd student life is extremely busy :).
This module is based on ns2's 802.11 module. So I may like if you have
a missing memory in ns2.
I don't know how to attach a file, so I just put my website link here.

Thanks,
Kim.

You might want to consider proposing it for review: http://www.nsnam.org/developers/contributing-code/code-reviews/

 

Thanks,

Do you have any documentation for the code?

Hi, Junseok,

Sorry to bother you.

I am a Mphil student from The University of Hong Kong doing some
research on Wireless Networks. As I want to implement my idea in NS-3
Simulator, I googled a lot and found you have done some thing before.

Since I am a newbie on NS-3, it's quite hard for me to handle this
complex simulator in a short time. I have gone through the code in wifi
module, and have some question about the code.

I have found that seems NS-3 do not follow the standard when node
content for the access of channel. I mean, it should follow the step of
DCF, wait for DIFS, random backoff, and when there is other sending
packet in channel, the backoff should shut down wait another DIFS, BUT
the code there seems do not follow the mechanism. It does not wait DIFS
to start the random backoff.

Is that mean the NS-3 simulator donot follow the standard when implement
by code?? If I need to implement the DCF, all the modules need to be
write by myself?? That's a huge work for me.

BTW, I have download your code about simple CSMA/CA protocal. I will try
it tomorrow, but I am not sure it can work perfectly as I am using
ns-3.19 the lastest version for now.

And, I am focusing on Power Saving in WLAN, really hope to discuss with you.

Thank you very much! Really need your help!

Best Regards,

Leo
