CW Differentiation acc. to nodes

[Surya Gangwar]

I want to set up a scenario in such a manner that differentiation is
on basis of nodes. Like, a boolean parameter for a node is introduced
and if the parameter is true then initial value of CW = 2
else it should be initialized to 3.
Is the idea feasible?
Where should I make amendments to incorporate this?
Please help.

Thanks & Regards

You have the code and you can do whatever you want with it. 

You'll have to introduce a new boolean parameter to the 802.15.4 MAC and change the code of that MAC to use the parameter how you want to.
