[ns] How to use promiscuous mode?

[Yunjung Yi <yjyi@CS.UCLA.EDU>]

Hello.
Right now, I want to modify AODV implementation in ns-2 to simulate my
idea. Basically my idea requires every node overhear packets all the time,
so AODV should receive packets promiscously like DSR does.
I'm wondering what I need to do to support this functionality.
I guess I need to change the tcl/tk script files.. but I don't know how
to.
I changed
"Simulator instproc create-wireless-node args " function in
tcl/lib/ns-lib.tcl

from
        if {$routingAgent_ != "DSR"} {
                $node attach $ragent [Node set rtagent_port_]
        }
to


        if {$routingAgent_ != "DSR"} {
                $node attach $ragent [Node set rtagent_port_]
                if {$routingAgent_ == "AODV"} {
                  $node instvar ragent_ mac_
                  $ragent_ install-tap $mac_(0)
                }
         }

But it's not working and I got error when I run test case.

Pls. let me know how to do.

Thank you so much.
