Respected Sir/Madam,
I am trying to study the effect of Scheduler Policies on Energy
Consumption of Portable Device.

There are lots of people currently working on this, and have been for
many years.  I know of at least 3 complete implementations at the
moment (two of which ship in some Android phones), so I would suggest
working with one of those groups to try to get their code merged into
the Linux kernel.  To create a 4th implementation would seem like a bit
of a redundant effort.

Search the archives of lwn.net for details about this if you are
interested.

good luck!
