As far as I understood, you are trying to generate a simulation setup for a wired-wireless scenario where the AP is a gateway to the wired domain. Please take a look at Marc Greis' tutorial, chapter 10. Base station (described in detail in that chapter) provides the connection of the wireless domain to the wired domain (that may be what you have meant by 'connection to exterior').
You may define a mobile node as an AP as stated in the thread you mentioned. But this won't enable the node to be a gateway to the wired domain. When the AP is defined, all WLAN traffic, whether it is destined to another wireless node or not, will traverse the AP as the first hop. Hope this helps.

However, there're also AP (Access Points) in this network to provide connection to exterior. The problem is that I don't know how to simulate an AP. I tried to search on the web and the only example is at http://mailman.isi.edu/pipermail/ns-users/2005-June/050548.html but I don't understand the reply in that thread. Taking a look at ~ns/tcl/lib/ns-mobilenode.tcl I found nothing to make a MN become an AP (from line 55: Node/MobileNode instproc init args). Might anyone tell me, or give me a link, how to make a MN become an AP ? Thanks in advance. -- Hai-Nam http://www.jcisio.com
