The development of Distributed Real-Time Embedded Systems requires solutions that are able to address constraints imposed on design, such as low energy consumption, reduced area, and timing requirements, but also keeping a flexible and reusable approach to cope with the growing complexity of these systems. This paper shows how the Real-Time Specification for Java (RTSJ) event service combined with a task scheduler modified to control a Dynamic Voltage Scaling (DVS) mechanism can improve a multiprocessor communication service and provide energy optimization. Furthermore, the unpredictability inherent to communication is reduced, improving real-time properties. An illustrative example of message passing is used to demonstrate the concept.
