    HyScale: A Hybrid Optical Network Based Scalable, Switch-Centric Architecture for Data Centers

    Data Center Network architectures (DCN) are evolving for increased scalability, performance, and low network complexity. In this paper, the authors propose HyScale, a switch-centric DCN architecture using hybrid optical networks. HyScale employs Optical Burst Switching and Optical Circuit Switching technologies for transmitting low and high volumes of data respectively in...

    Improving the Testing and Testability of Software Product Lines

    Software Product Line (SPL) engineering offers several advantages in the development of families of software products. There is still a need, however, for better understanding of testability issues and for testing techniques that can operate cost-effectively on SPLs. In this paper, the authors consider these testability issues and highlight some...

    Feature Interaction Faults Revisited: An Exploratory Study

    While a large body of research is dedicated to testing for feature interactions in configurable software, there has been little work that examines what constitutes such a fault at the code level. In consequence, the authors do not know how prevalent real interaction faults are in practice, what a typical...

    A Survey on Cyber Security for Smart Grid Communications

    A smart grid is a new form of electricity network with high fidelity power-flow control, self-healing, and energy reliability and energy security using digital communications and control technology. To upgrade an existing power grid into a smart grid, it requires significant dependence on intelligent and secure communication infrastructures. It requires...

    Collaborative Relay Beamforming for Secure Broadcasting

    In this paper, collaborative use of relays to form a beamforming system with the aid of perfect Channel State Information (CSI) and to provide communication in physical layer security between a transmitter and two receivers is investigated. In particular, the authors describe decode-and-forward based null space beamforming schemes and optimize...

    Secure Communication Over Fading Channels with Statistical QoS Constraints

    In this paper, secure transmission of information over an ergodic fading channel is explained in the presence of statistical Quality of Service (QoS) constraints. The authors employ effective capacity to measure the secure throughput of the system, i.e., effective secure throughput. They assume that the Channel Side Information (CSI) of...

    A Novel Model for Synthesizing Parallel I/O Workloads in Scientific Applications

    Understanding I/O workload characteristic is critical in system modeling and simulation-based performance evaluation. Identifying representative I/O workloads allows researchers to fairly compare existing designs and faithfully evaluate new alternative ones. One of the challenging issues in performance evaluation of parallel storage systems through synthetic-trace-driven simulation is to accurately characterize the...
