The problem of energy consumption is topical in every sphere of human activity nowadays. This problem is especially important for IT (information technologies), where the amount of data that needs to be processed is growing every day. In this paper PCPB (Power Consumption and Performance Balance) algorithm has been proposed. It is an energy-aware scheduling algorithm which is aimed at reducing power...
In the paper is discussed the basic quality of the mobile data network Quality of Service (QoS), among which the most frequently used data rate, packet delay in deviation from the mean delay in the transmission of packet loss rate and packet distortion. Considered the operational level of quality assessment data services, and proposed to characterize the quality of integral quality index KQI. The...
The Internet-of-Things (loT) is penetrating in every sphere of a human life simplifying his everyday life and rising his labor efficiency. There are a lot of challenges on its way of development. Additional challenges appear when considering the IoT systems with nomadic units. The paper is dedicated to the problem of data collecting, processing and storing in the IoT system containing nomadic units...
With wide deployment of new mobile network equipment and increasing requirements to network reliability, the destroying events such as power outage or disaster have become a serious threat to the current mobile networks. Such events can at the same time destroy all equipment in a particular land zone and affect network services for a long time. That is why so important to develop disaster-resilient...
Performance-to-energy tradeoffs in distributed computing are discussed. Performance models are examined. Energy optimization can be reached under use of the advanced technologies like IoT.
In this paper it was reviewed several existing investigations about minimization power consumption of data centers. It was suggested several approaches of task distribution in computing networks to minimize power consumption and management system for such networks.
Today, the world has gotten to be very reliant on the services provided by the mobile communication. All present day mobile communication systems implemented in a hierarchical manner. Such systems are extremely unstable, in light of the fact that disappointment of one of the components may cause disappointment of the whole system. Different damaging impacts have diverse consequences on the extent...
Changeable requirements for modern services, provided in global environment, and their constant reengineering demand dynamic composition of services which is able to estimate changes of various parameters, both functional and non-functional ones. Web Services Agreement is a convenient way to contain QoS parameters, but state-of-the-art SLA-aware methods are not able to support all classes of nonfunctional...
Characteristic of Internet based information system (IBIS) is represented it's the main points of its functioning and design are discussed. The requirements to IBIS information-computation processes are specified and IBIS architecture for requirements satisfaction is suggested.
