Hi all,
I found the the answer to my question in
http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2005-January/007229.html
Actually, it is not necessary to have a SensorAppC component since in my
case, i am using another component to wire this SensorC component.
So, what I did was, wired the SensorC to my other component WSNAppC.
Thanks everyone who spends their time on this question.
Best Regards!
Lasanthi
