Energy reduction is critical to increase the mobility and battery life for today's pervasive computing systems. At the same time, energy reduction must be subject to the real-time constraints and Quality-of-Service (QoS) requirements for multimedia applications running on these systems. This paper presents a novel run-time scheduling approach to reduce the system-wide energy consumption for such systems. In this paper, the multimedia applications are modeled using a popular weakly hard real-time model, i.e., the (m;k)-model.
