Re: [Autoconf] aspects of multi-hop wireless communication

["Seung Yi" <[e-mail]>]

I'm sorry but it sounds even more confusing to me.

I'm not sure what to call it but it seems to describe the hidden
terminal problem to me. Or, it's simply saying that the link (or
whatever you want to call the "S") is of non-broadcast flavor because
R1 and R2 can expect to hear each other only when the medium itself
provides broadcast capability as in the Ethernet.
