Abstract It is challenging to reduce the processor power
consumption while meeting the processor resource
requirement of distributed multimedia applications in
portable computers. This paper presents a middleware
framework coordinating the Processor/Power Resource
Management (PPRM) in mobile computing environment. Our
framework has four major contributions: (1) providing a
power-aware resource reservation mechanism, where
admission control is based on the processor utilization and
power availability; (2) adjusting the speed and corresponding
power consumption of the processor upon events, triggered by
the change of the system workload or power availability; (3)
updating reservation contracts of multimedia applications to
maintain their resource requirements while adjusting the
