a question about judging whether the MAC(802.11 used in Ad Hoc) is idle

Dear all,
I'm sorry for my poor English first, because it's not my mother tongue.Maybe I should improve it.
About the method of judging whether the meduim is idle, there is a paper proposing three conditions:
1. NAV's value is less than the current time
2. receive state is idle
3. send state is idle
My question is whether satisfying the three conditions above is suffient.
I'm afraid that there may be an exclusive situation like that: the PHY senses the interference but the MAC thought the meduim is IDLE(because it has not received RTS/CTS and the rx_state and tx_state all both IDLE). So the MAC prepares to send message, while the PHY layer is not really IDLE.
Am I right?
 
Many thanks!
Best regards.

MANET Pronunciation

Dear List,

I would like to know how to properly pronounce MANET. I've come to
understand there is some history behind the term which may affect how
someone says the term. Professionally, I've heard MANET pronounced three
different ways: First as "ma-net" where the "N" sound is made only made
once between the syllables. Second as "man-net" where the "N" sound is
present in both syllables. Third as "ma-nay" as in the nineteenth
century French painter Edouard Manet.

I apologize if this question seems flippant but knowing how to properly
pronounce terms is important and there is some history behind term's
pronunciation. I'd like to know if there is a general consensus within
the group as to where the pronunciation has been taken.

Thank you,
Michael Knapp

Re: MANET Pronunciation


Hello Michael,

I'm sure you would get a variety of answers and there
does not seem to be consensus.

What I "like" to do is to use the painterly pronunciation
as "normal", and use the "man-net" choice when it seems
that I really have to emphasize that I am talking about
networks.  So, for instance, I'd prefer the first option
when talking about the [manet] working group.

Consistency... bah, humbug.

Regards,
Charlie P.

Re: MANET Pronunciation

There is variety here and that is ok by me.. 
In my experience it is generally pronounced "man-nay"
I pretty much do what Charlie does if audience needs it, I might have to say "man-net"

You say toe-may-toe ... I say toe-ma-toe
You say poe-tay-toe ... I say poe-ta-toe

----------------------------
For me, I initially liked the Edouard Manet pronunciation when we first created the term back in the day.

In one of my first presentations on manet problem/concepts 11th IEEE Computer Communications Workshop
Sep 24, 1996 I actually used a
portrait of Edouard and I discussed some "off-the-cuff" analogies.

Perhaps a weak attempt at humor?

We really don't need a thread on this but ...
While MONET is considered the father of impressionism style in art, MANET is considered its grandfather.
Analogies to routing style?? You decide.

.."Impressionism" style tends to use less detail to impress a form.

.."Impressionism" style recognized that light and shadow are often seen in glances and are everchanging.

.."Impressionism" style may appear sloppy partially due to the artist's need to work quickly in dynamic,
outside conditions.

Random trivia...As some may recall, the movement was sharply rejected by the established "Salon de Paris"
for many years and a
"Salon de Refused" was formed.
---------------------------

Hmmm....

I follow pretty much the same rule.

Re: MANET Pronunciation

I rather liked Joe's account of the name origin. I guess
the term has been in use for quite some time now...

About the 802.11 SIFS value

Hello,

I have two questions about the value of SIFS. 

1- Why it is not set to a zero?
2- how does any OS decide its value?

Thank you,

Re: About the 802.11 SIFS value

> 1- Why it is not set to a zero?

Primarily this is to allow for processing time. The 802.11 Spec has to
allow for multiple implementations and allow them to work together.
While the relatively large values for SIFS may seem extreme in one
system, they may be challenging to meet in others. (At least when the
spec was written).

> 2- how does any OS decide its value?

Each 802.11 Phy has defined values. The 802.11g defines the SIFS to be
10us. The SIFS is the same for all data rates, again to allow multiple
user types equal access.

A quesion about AODV

Hi all,
Here si a question about AODV.
in AODV::command(), there is code as below:
   
    if(argc == 2){
        ......
        if(strncasecmp(argv[1], "start", 2) == 0){
                htimer.handle((Event*)0);   // for periodically sending hello packets
                ......
        }
        ......
    }
 
While in my OTcl scripts for simulation, there is no code like $aodv_  " xxx start", but only
    $ns_  at 10.0 "$ftp_ start"
 
I wonder how could this  make the code for periodically sending hello packets work?
 
Thank you!
 
Regards
Shao
