The increasing demand on higher transmission speed and shorter delay in wired networks becomes critical in recent communication networks. However, the capacity of transmission link is limited by the method of transmission. In this paper, aiming at the situation of large scale networks, an overview of the network optimization based on big data and traffic prediction is given in our proposed work. In...
The reduction of energy consumption in base stations becomes popular recently. However, it is difficult to reduce energy consumption under the constraint of Quality of Service (QoS). In this paper, we propose a novel energy aware control method to adjust the radius that the base station provide the service in wireless downlink systems, the optimal radius of the base stations provide service could...
Today's best-effort Internet with "one fits all" principle comes to an impasse. Addressed to different QoS requirements of today's network services, we propose a QoS oriented Network Architecture that bases on network virtualization. It provides multiple virtual networks deploying on the same substrate, each is designed with a special designing goal and is running a customized protocol....
In order to improve the accuracy of the vertical handoff decision-making and efficient utilization of wireless network resources in radio heterogeneous network, this paper proposes a hierarchy multiple attribute decision with possibilities (HMADP) method based on service. This method uses analytic hierarchy process ( AHP ) and multi attribute decision making with possibility (MADMP). The AHP reflect...
Layered streaming in overlay networks has drawn great interests since not only can it accomodate large scales of clients but also it handles client heterogeneities. However, to our knowledge, there's still a lack of overlay construction (i.e. neighbor selection) approach suited for layered streaming, because i) In existing works neighbors are selected only based on their network conditions. However,...
QoS-based service selection mechanisms will play an essential role in service-oriented architectures, as e-business applications want to use services that most accurately meet their requirements. However, current techniques provide no support for actually making rational selections. In this paper, we develop a multiagent framework for QoS-based Web services selection, through a combination of the...
