With the popularity of smart devices in a variety of actions to drive more usage of wireless broadband networks. OTT refers to delivery of video, audio and other media over the Internet. The video-related applications and services are major challenges that impact the network performance in the future. It is important to achieve network and service traffic offloading to overcome high-speed, real-time,...
The centralized Radio Access Networks (RAN) architecture is one of the promising approaches to reduce energy consumption of Base Stations (BSs), while BS sleeping technology can achieve further energy savings. In this paper, a power consumption model of the centralized RAN architecture is proposed, which has not been addressed before. Moreover, we analyze the existing BS sleeping schemes and compare...
As the rapid development of wireless communication technologies and the widespread popularity of smart terminals, traffic and demands of the mobile network grow exponentially, moreover the deployment of small cells in current heterogeneous networks becomes denser and denser. These bring lots of signaling overhead and too much energy consumption, in addition these challenge the robustness of mobile...
In this paper, a hardware implementation of Support Vector Machine (SVM) classifier for acceleration has been proposed based on pipelined adder, in which the speedups outperform other existing architectures. The adder whose critical path has been efficiently shortened by pipeline technology, constituted the main arithmetic elements in SVM processing. Therefore, a higher processing frequency and throughput...
A novel circuit architecture for variable latency adder based on present and transitional states prediction (PTSP) method is presented in this paper, for taking the low power benefits of voltage-over-scaling. With the scaling down of CMOS technology, failure from process variation and high power consumption has become severe problem in VLSI design and the traditional conservative methodology is about...
Cloud computing promises an open and promising environment where customers or users can utilise and deploy IT services in a pay-as-you-go style while saving huge capital investments on their own IT infrastructure. The openness and virtualisation features in cloud environments make privacy protection and preservation be a challenging issue. Currently, in existing privacy protection and preservation...
Software solutions for certain complex problem areas such as claims adjudication and fraud detection are hard to build using imperative programming languages and even harder to maintain and change. In light of this, enterprises are turning to Rule-Based Expert Systems to provide a solution. However, to realize the full potential of this, the technology for mining and articulating the knowledge need...
There is a compelling need for highly customized Domain Specific Languages and Business Vocabulary in certain industries such as insurance, mortgage, and finance to enable Knowledge Workers to articulate and to automate complex rules pertinent to their areas of function within their companies. Rule Engine vendors attempt to provide a solution to the problem by selling an integrated Rules Engine and...
In this paper, a jointed preamble/boundary detection and fractional carrier frequency offset (CFO) estimation design is presented which supports dual SC/HSI modes of IEEE 802.15.3c applications. Based on correlation based algorithms which utilizes the structure of preamble, an efficiency architecture is proposed which realizes synchronization detection with a sequential detection scheme and only single...
This paper proposes the use of service-oriented architecture and Web service technology, to address the current energy control problem. We propose a extended hierarchical model to organize the integrated smart grid system connected over the IP cloud, so that coordination and cooperation of all information systems are achieved autonomously and provides consumers with a carbon network management platform...
Up to now, the “4+1” View model, which has been approbated widely, has become an authoritative method to depict the architecture of software. In pragmatic application, however, this comprehensive description has not been applied well and the relevant research about it has ceased for long time. In this paper, we analyze the core conceptions of the “4+1” View model, and discuss its advantages and limitations...
The Web service resource framework (WSRF) announced in January 2004 is a new mechanism to express how web services interact with the stateful resources, and it has achieved the fusion of Web services and grid services. For the grid application development, WSRF.NET is much easier than Globus Toolkit 4 and it is based on Windows. As WSRF.NET doesn't provide an available scheduler, we introduce Condor...
This article gives a detailed description of the Condor system-a distributed scheduler. A typical Condor system consists of four components: A Condor pool, the central manager, submitting machine and execution machine. The ClassAd is a flexible representation of the characteristics and constraints of both machines and jobs in the Condor system. Matchmaking is the mechanism by which Condor matches...
In this paper, after analyzing the requirement of aspect-oriented modeling, a meta-model based on UML extension profile for AOM is proposed, a framework of aspect-oriented modeling (AOMF) with UML is built, and a simple and feasible way to model the dynamic behaviors of aspect-oriented software is presented. Furthermore, a case study is presented to demonstrate the effectiveness and advantages of...
A low power high speed Read-Out Integrated Circuit (ROIC) for a short-wave Infra-Red Focal Plane Array (IRFPA) is designed as a prototype for 1024 times 1024 image system. Ripple integration and readout scheme as well as highly efficient power management are introduced to this design in order to decrease total power. To further increase the readout speed while decrease the power dissipation, a novel...
