    Abstract anzeigen

    The existing electromobility (EM) is still in its fledgling stage and multiple challenges have to be overcome to make Electric Vehicles (EVs) as convenient as combustion engine vehicles. Users and Electric Vehicle Fleet Operators (EFOs) want their EVs to be charged and ready for use at all times. This straightforward goal, however, is counteracted from various sides: The range of the EV depends on the status and depletion of the EV battery which is influenced by EV use and charging characteristics. Also, most convenient charging from the user's point of view, might unfortunately lead to problems in the power grid. As in the case of a power peak in the evening when EV users return from work and simultaneously plug in their EVs for charging. Last but not least, the mass of EV batteries are an untapped potential to store electricity from intermittent renewable energy sources. In this paper, we propose a novel approach to tackle this multi-layered problem from different perspectives. Using on-board EV data and grid prediction models, we build up an information model as a foundation for a back end service containing EFO and Charging Station Provider (CSP) logic as well as a central Advanced Drivers Assistant System (ADAS). These components connect to both battery management and user interfaces suggesting various routing and driving behaviour alternatives customized and incentivized for the current user profile optimizing above mentioned goals.

    Virtual Energy Information Network: A Resilience Perspective

    e&i Elektrotechnik & Informationstechnik (Special Issue on ’Smart Grid and Security’), vol. 130, no. 4-5, pp. 121-126

    2013

    Abstract anzeigen

    Increasing demand in energy consumption, missed modernisations, and the increasing difficulties in predicting power production due to volatile renewable energy sources (e.g., based on wind or sun) impose major challenges to the power grid. Power supply and power demand are closely interconnected with the need to maintain the power grid in a stable state with a sufficient quality of power. This requires energy-relevant information to be exchanged through the so called Energy Information Network. Communication, however, is challenging within the Energy Information Network due to privacy, security, resiliency, and quality-of-service requirements. Particularly, the resilience of communication within the Energy Information Network needs to be considered to maintain the power grid in a stable and controlled state. This paper suggests a Virtualised Energy Information Network (VEIN), where the Energy Information Network is divided into multiple virtual networks that run over a common substrate network. Furthermore, this paper discusses benefits of this approach in terms of privacy, security, and resilience and points out open research questions.

    Survey on Energy Efficiency in Office and Residential Computing Environments

    Journal on Green Engineering, vol. 2, no. 3, pp. 255-272

    2012

    Abstract anzeigen

    Cloud Computing is today's most emphasized Information and Communications Technology (ICT) paradigm that is directly or indirectly used by almost every online user. However, such a great significance comes with a support of a great infrastructure that includes large data centers comprising thousands of server units and other supporting equipment. Their share in power consumption generates between 1.1% and 1.5% of the total electricity use worldwide, and is projected to rise even more. Such alarming numbers demand rethinking the energy efficiency of such infrastructures. However, before making any changes to the infrastructure, an analysis of the current status is required. In this paper we perform a comprehensive analysis of an infrastructure supporting the Cloud Computing paradigm with regards to the energy efficiency. First, we define a systematic approach for analysing energy efficiency of most important data center domains, including server and network equipment, as well as cloud management systems and appliances consisting of a software utilized by end users. Secondly, we utilize this approach for analysing available scientific and industrial literature on state of the art practices in data centers and its equipment. Finally, we extract existing challenges and highlight future research directions.

    Integrating Mobile Cellular Devices into Popular Peer-to-Peer Systems

    Telecommunication Systems, vol. 48, no. September, pp. 173-184

    2011

    Abstract anzeigen

    Today, peer-to-peer content-distribution networks are highly popular among users that have stationary computers with high-bandwidth Internet connections. Mobile devices (e.g. cell phones) that are connected to the Internet via cellular-radio networks, however, could not yet be launched into this field to a satisfactory extent. Although most mobile devices have the necessary hardware resources for joining peer-to-peer content-distribution networks, they are often not able to benefit from participation in an energy efficient way, due to limitations caused by mobility. In this work, mobile devices are identified as providers of advanced mobile features and services that are usually not available to computers in stationary networks. These mobile features and services can be exchanged for services in peer-to-peer networks, turning mobile devices into valuable trading partners. Partnership schemes are set up to define the way of a fair cooperation between mobile devices and other peers. A novel peer-to-peer architecture is suggested that applies partnership schemes to a well-established peer-to-peer content-distribution network and facilitates the integration of mobile devices.

    An Energy-Consumption Model for Energy-Efficient Office Environments

    Future Generation Computer Systems, vol. 27, no. 8, pp. 1047-1055

    2011

    Abstract anzeigen

    The rising costs of energy and the world-wide desire to reduce CO2 emissions has led to an increased concern over the energy efficiency of information and communication technology. Whilst much of this concern has focused on data centres, also office hosts that are located outside of data centres (e.g., in public administration or companies) have been identified as significant consumers of energy. Office environments offer great potential for energy savings, given that computing equipment often remains powered for 24 hours per day, and for a large part of this period is underutilised or even idle. This paper investigates the energy consumption of hosts in office environments, discusses the potential of energy savings and proposes an energy-efficient office management approach based on resource virtualization, power management, and service consolidation. Different virtualization techniques are used to enable management and consolidation of office resources. Idle services are stopped from consuming resources on the one hand and (underutilized) services are consolidated on a smaller number of hosts on the other hand.

    Virtualisierung im Future Internet - Virtualisierungsmethoden und Anwendungen

    Informatik-Spektrum, vol. 33, no. 2, pp. 186-194

    Abstract anzeigen

    Das Future Internet stellt sich der Herausforderung, die Verknöcherung und die Unzulänglichkeiten des heutigen Internets zu überwinden. Es soll beispielsweise robust, zuverlässig und fehlertolerant sein und dabei Dienste auf energieeffiziente Weise erbringen. Zusätzlich müssen auch neue Anforderungen antizipiert werden, die zukünftige Dienste und Netze stellen, um der Entwicklung von neuen Diensten und Protokollen nicht im Wege zu stehen. Erforderlich ist hierbei die Entwicklung einer äußerst variablen und rekonfigurierbaren Netzwerkarchitektur, die eine möglichst einfache und autonome Netzwerkverwaltung mit einschließt. Die Virtualisierung von Host- und Netzwerkressourcen stellt in diesem Zusammenhang eine der Schlüsseltechnologien dar, mit der diese notwendige Flexibilität erreicht werden kann. Virtualisierung verbirgt die Komplexität von physikalischen Netzwerkinfrastrukturen und stellt homogene, flexible und dynamisch rekonfigurierbare virtuelle Ressourcen zur Verfügung. Dieser Artikel gibt einen Überblick über verschiedene Host- und Netzwerkvirtualisierungsmethoden. An mehreren Beispielen wird aufgezeigt, wie verschiedene Herausforderungen angegangen werden können, die sowohl im heutigen Internet als auch im Internet der Zukunft eine Rolle spielen.
