Service Level Agreements (SLAs) are powerful instruments for describing such contracts. SLA-aware resource management is the foundation for realizing SLA contracts within the Grid. OpenCCS is such an SLA-aware RMS, using transparent checkpointing to cope with resource outages. It generates a compatibility profile for each checkpoint dataset, so that the job can be resumed even on resources within the Grid. However, only a small number of Grid resources comply to such a profile. This paper describes the concept of virtual execution environments and how they increase the number of potential migration targets.The paper also describes how these virtual execution environments have been implemented within the OpenCCS resource management system.","lang":"eng"}],"department":[{"_id":"27"}],"user_id":"15274","_id":"1976","language":[{"iso":"eng"}]},{"_id":"1977","user_id":"282","status":"public","publication":"Kirche & Recht, Zeitschrift für die kirchliche und staatliche Praxis","type":"journal_article","title":"Europa und die Religionen","publisher":"BWV Berliner Wissenschaftsverlag ","date_updated":"2022-01-06T06:54:12Z","date_created":"2018-03-29T11:26:32Z","author":[{"first_name":"Dieter","last_name":"Krimphove","id":"282","full_name":"Krimphove, Dieter"}],"year":"2008","page":"89 – 126","citation":{"apa":"Krimphove, D.

We propose a solution by distributed random link exchange algorithms such that the overlay network can be a connected random graph or use a random graph as backbone.

While motion cost and communications cost constitute the primary energy consumers, each of them is investigated independently. By taking into account the power consumption of both entities, the overall energy efficiency of a system can be further improved. In this paper, the energy optimization problem of radio communication and motion is examined. We consider a hybrid wireless  network that consists of a single autonomous mobile node and multiple relay nodes. The mobile node interacts with the relays within its vicinity by continuously communicating high-bandwidth data, e.g. triggered by a multimedia application like video surveillance. The goal is to find the best path such that the energy consumption for both mobility and communications is minimized. We introduce the Radio-Energy-Aware (REA) path computation strategy by utilizing node mobility. Given the starting point, the target point and the position of the relays, our simulation results show that the proposed strategy improves the energy efficiency of mobile node compared to the Motion-Energy-Aware (MEA) path constructed based only on the mobility cost.
