Gerenciamento dinâmico de energia para interfaces de redes.

Abstract

Constant advances in hardware technologies, software, have made mobile computing systems increasingly necessary in our daily lives. The development of applications increasingly needed in our daily lives. Developing increasingly complex applications for these computer systems, such as video and game editing, requires more processing power. Increasing the number and complexity of these applications, coupled with the need for connectivity to some network interface, means higher power consumption and thus reduced battery life. Minimize power consumption, and thus lower battery life. Minimizing power consumption is a key problem in mobile system design as it directly affects battery life. However, the density of energy stored in batteries has not increased at the same rate as the performance required by these systems in recent years, so the mobile industry has made efforts to extend battery life by efficiently using available power and meeting user demands. One of the successful and widely used system-level techniques is Dynamic Energy Management (GDE). Applying this technique reduces power dissipation by shutting down or reducing the performance of system components when they are idle. However, employing this technique also results in performance loss due to the overload associated with device shutdowns and reclosing. An efficient management policy should therefore seek to maximize energy savings while keeping the performance penalty within acceptable limits.
