Prediction of energy consumption behavior in component-based distributed systems

UnrestrictedComponent-based distributed systems are increasingly deployed onto heterogeneous embedded platforms with limited battery resources. In this domain, it is crucial to provide an effective approach that enables an engineer to build energy-efficient component-based distributed systems throughout the entire development cycle spanning system design-time, construction-time, and runtime. To address this problem, this dissertation first presents a framework that (1) facilitates early estimation of the energy consumption induced by an architectural style in a component-based distributed system, and (2) consequently enables an engineer to use energy consumption estimates along with other quality attributes in determining the most appropriate style for a given distributed system during design-time.; As the second part of the solution, this dissertation provides a framework that allows the system engineer to estimate the energy consumption of a component-based distributed system implemented in Java at the level of its components, both during system construction-time and during runtime. We also present several practical applications of the framework, which can be effected either at system construction-time or at runtime for reducing the distributed system's energy consumption and consequently increasing the lifetime of the system's key services.; Our overall approach, composed of the above two estimation frameworks, has been evaluated empirically on a large number of distributed application scenarios, and produced very accurate energy consumption estimates. The dissertation concludes with several open research questions that will frame our future work
