Development of energy efficient distributed computer systems with self-contained remote modules

Development and growth of the electronics that use microcontrollers in different sites of application systems, such as distributed information-measuring systems, cause the search for more effective solutions to reduce energy consumption as well as modules usually consume from autonomous energy sources. In the article the problem of reducing the energy consumption of distributed computer systems with self-contained measurement modules based on microcontrollers through optimal scaling CPU frequency measurement of the module is considered. In the Paper the author solves the problem of energy efficiency improving of the system in aspects of CPU performing casual and periodic tasks. A mathematical model of this system was created, which considers energy restrictions of systems. For power optimization algorithm was used EDF. Performance of the system was experimentally verified on the basis of the measuring unit, which consists of selected piezoceramic element TsTS-19, Microstick for dsPIC33F Development Board the controller, Raspberry Pi Model B.
