Energy Management in Software Systems

Participants : Rémi Druilhe, Laurence Duchien, Lionel Seinturier [correspondant] .

Energy management and saving is a concern that spans the entire domain of information and communication technologies and sciences. Recently it has been recognized that to improve its efficiency, energy has to be managed, not only at the hardware level, but also at the level of software systems, especially in distributed environments. In his PhD thesis, Rémi Druilhe [11] proposes a new result with the HomeNap system for networked digital home environments. This work is the result of a collaboration with Orange Labs. HomeNap takes into account three main properties: heterogeneity, dynamicity and quality of service. HomeNap proposes an autonomic decision-making system to deal with the placement of digital services on networked devices. Based on the observation of relevant events, the system takes the decision to modify the distribution of digital services on devices in order to preserve a defined tradeoff between energy efficiency and quality of service. HomeNap participates to the long term objective of dealing with energy as a main steering factor for self-optimizing software systems.
