    Distributed Energy Efficiency in Future Home Environments

    Annals of Telecommunications (Special issue: Next Generation Network and Service Management), vol. 63, no. Oktober, pp. 473-485

    Abstract anzeigen

    In this paper, a new architecture for sharing resources among home environments is proposed. Our approach goes far beyond traditional systems for distributed virtualization, like PlanetLab or grid computing, as it relies on complete decentralization in a peer-to-peer (P2P) like manner and, above all, aims at energy efficiency. Energy metrics are defined, which have to be optimized by the system. The system itself uses virtualization to transparently move tasks from one home to another to optimally utilize the existing computing power. We present an overview of our proposed architecture, consisting of a middleware interconnecting computers and routers in possibly millions of homes using P2P techniques. For demonstrating the potential energy saving of distributed applications, we present an analytical model for sharing downloads, which is verified by discrete event simulation. The model represents an optimistic case without P2P overhead and fairness. The model allows to assess the upper limit of the saving potential. An enhanced version of the simulation model also shows the effect of fairness. The fairer the system gets, the less efficient it is.

    Mobility, Mobility Management Mechanisms, and a Mobile P2P Architecture

    Transactions on Automated Control Systems, vol. 1, no. Dezember, pp. 179-186

    2006

    Abstract anzeigen

    Mobility management mechanisms are used to provide mobility. Different kinds of mobility requiredifferent mobility management mechanisms. Common P2P applications are designed for fixed networks. Applying mobility to P2P applications is still a research issue. There are some approaches to improve P2P overlay networks in order to support the mobility of users
