[ns] Wireless + Exponential/Pareto Traffic Generator doubt

[sameer tilak <sam_tilak@yahoo.com>]

Hi All,
I am trying to simulate Exponential Traffic in
wireless Environment. 
The relevant code fragment is:

    set src0  [new Agent/UDP]
    set sink0 [new Agent/UDP]
    $ns_ attach-agent $node_(1) $src0
    $ns_ attach-agent $node_(0) $sink0
    $ns_ connect $src0 $sink0

    set expo [new Application/Traffic/Exponential]
    $expo set packetSize_ 210
    $expo set burst_time_ 500ms
    $expo set idle_time_  500ms
    $expo set rate_ 200k
    $expo attach-agent $src0

    $ns_ at 1.0 "$expo start"

I am getting the following error:
(null)- invalid packet type (exp).
I am getting the same error with Pareto as well.

The same thing works fine if I change the agent to
CBR...

Please tell me do I need to make some changes during
the configuration of the ndoe itself ?

Regards,
-Sameer.
