Microgrid equipped with heterogenous energy resources and a bank of energy storage
devices presents the idea of small scale distributed energy management (DEM). DEM …

In information systems, applications are required to be realized in the digital ecosystems,
high performance systems, and scalable systems. In these applications, a client first selects …

While distributed computing infrastructures can provide infrastructure-level techniques for
managing energy consumption, application-level energy consumption models have also …

Electric energy consumed by computers, especially servers in scalable clusters has to be
reduced to realise eco society. In this paper, we first propose a multi-level power …

It is critical to reduce the energy consumption of information systems to realize green
societies. The IoT (Internet of Things) is so scalable that millions to billions of computers and …

Scalable and fault-tolerant information systems like cloud systems are realized in server
cluster systems. Server cluster systems are equipped with virtual machines to provide …

Abstract The FC (Fog Computing) model is proposed to efficiently realize the IoT (Internet of
Things), where fog nodes support application processes to handle sensor data in addition to …

Process replication can provide reliable and available distributed application services. On
the other hand, a large amount of electric energy is consumed to provide replicated …

With the increasing scale of cloud data centers (CDCs), the energy consumption of CDCs is
sharply increasing. In this article, an efficient energy-saving strategy is proposed for CDCs …

In information systems, processes requested by clients are performed on servers in a cluster
of multiple servers. Here, not only QoS (quality of service) requirements like response time …
