Dear Falahati, Doing a flow chart for 802.11 MAC for NS2 is very good. It is not a easy task though as if you go deeper you will see 3 different flows you must understand.
1. The event flow - How one event calls another 2. The state flow - For instance, how MAC states e.g tx_state or rx_state changes, when tx_active activated 3. Timer Management flow - RxTimer, TxTimer, DeferTimer, BackOffTimer etc managed. The flow chart you have shared, is incomplete as not explored all the branches, missing some process and have errors, thus the given flowchart is not good to understand the 802.11 MAC. I have reviewed the first block, Refer: http://www.pixentral.com/show.php?picture=1WK7gXjz96e6klBBw32eI0KcBS2zro Not to get disheartened on the effort. Suggest you to continually working on it, eventually it will be correct. Good Luck. rgds Saravanan K On Fri, Dec 7, 2012 at 10:12 AM, M Falahati <md.falah...@gmail.com> wrote: > > Hello > > Thanks for your reply. > > Ms Bostanipour, I hope that continuation of our discussion solve some > problems. > > Yesterday, i was drawing the flowchart with my viewpoint of NS-2 codes. > > Please see the flowchart from > here<http://www.pixentral.com/show.php?picture=11IMy2iqu2fgUFjOfZDnEa1LoRLl0>. > > I think this flowchart is good for better understanding of Mac-802_11 > mechanism. > > *I have a suggestion:* If you agree, please check this flowchart that we > can continue our discussion about Mac-802_11 mechanism in details. > > *Note:* this flowchart has drawn to present the send mechanism of > "broadcast data packets" in Mac-802_11. > > Sincerely Yours.
