[ns] attaching snoop to a node

[Gary Leung <kfleung@eee.hku.hk>]

Hi all,

I am new on ns.
I am constructing a network topology as following:

n1----- n2  -  -  - n3

where n2 is a basestation. n3 is a static node(will not move). The link
between n1 and n2 is wired while n2 and n3 is wireless.
According to the snoop.tcl, I have to construct a lan object by
providing a parameter nodelist and other necessary parameters. After
that I can "attach" the
snoop agent by using method "addNode".

Is using object "lan" the only way to attach a snoop agent to a node?
any other approach? For such a network topology mentioned above, what
tcl script I need?

Thank you very much in advance.

Rgds,
Gary Leung
