Hi Ejaz,
In fact, the CRCN patch has an array that maintains the number of channels
at the routing layer. When you run any other routing protocol except the
aodv or wcett provided with the CRCN patch, it will give you an error.
Because, other protocols are not configured to work with multiple channels.
Thanks

Dear All,
I am facing problem in simulating the PUMA in multiple radio multi channel
environment. I have ported PUMA multicasting patch for wireless to ns-2.31.
Its working well when i ran its example. I have also integrated the crcn
patch for cognitive radio network in ns-2.31 which is also working well on
its own example. Now i am writing my own example for checking the PUMA
performance over crcn mac. It is not working and giving an error.

It is giving an error on add-channel function and pointing that can't set
chan(0): variable isn't array. But sir it does not give any error when it
run on crcn example.
Waiting for useful replies.
