[ns] Mac broadcast in wireless lan

[prashant <iscp9140@nus.edu.sg>]

Can someone please tell me how to do mac broadcast in wireless lan. I
have my own protocol agents sitting on mobile nodes. I wish to broadcast
packets to all the mobile nodes in the lan. My agent does not specify
any destination address. I have tried
 Classifier/Mac set bcast_ 1
but it doesn't work.
I have also tried attaching 'Replicator' to all the nodes but even that
doesn't seem to work. 
In both the above cases, the packet is not delivered to any of the node. 
I am not using 'connect' to connect the agents as I want broadcast.
There does not seem to be any flaw in my agent implementation or in
other parts of my script as the whole thing works fine if I send packets
with one node connected to other.

Thanks in advance
