    Legibility, Privacy and Creativity: Linked Data in a Surveillance Society

    In this paper the authors look at the issue of privacy and anonymity through the prism of Scott's concept of legibility i.e. the desire of the state to obtain an ever more accurate mapping of its domain and the actors in its domain. They argue that privacy was absent in...

    Representing Supply Chain Events on the Web of Data

    The Electronic Product Code Information Service (EPCIS) is an EPC global standard, that aims to bridge the gap between the physical world of RFID tagged artifacts, and information systems that enable their tracking and tracing via the Electronic Product Code (EPC). Central to the EPCIS data model are \"Events\" that...

    Specification and Quantitative Analysis of Probabilistic Cloud Deployment Patterns

    Cloud computing is a new technological paradigm offering computing infrastructure, software and platforms as a pay-as-you-go subscription based service. Many potential customer's of cloud services require essential cost assessments to be undertaken before transitioning to the cloud. Current assessment techniques are imprecise and rely on simplified resource requirements that fail...

    Investigation of PHY, MAC and APP Layers for Adaptive and Cross-Layer Optimization in IEEE802.11 WLAN

    Due to huge popularity of portable terminals based on Wireless LANs and increasing demand for multimedia services from these terminals, the earlier structures and protocols are insufficient to cover the requirements of emerging networks and communications. Most research in this field is tailored to find more efficient ways to optimize...

    Automatic Visualization Pipeline Formation for Medical Datasets on Grid Computing Environment

    Distance visualization of large datasets often takes the direction of remote viewing and zooming techniques of stored static images. However, the continuous increase in the size of datasets and visualization operation causes insufficient performance with traditional desktop computers. Additionally, the visualization techniques such as Isosurface depend on the available resources...

    Bounds on End-to-End Performance of Networks Employing Erasure Control Coding

    In packet-based IP networks, including wired and wireless sections, the end-to-end performance is governed by the protocols set at the transport layer, such as TCP and UDP. The traditional TCP's problems stem from the fact that retransmission takes place as long as a TCP segment is lost for whatever reason,...

    QoS Performances of IEEE 802.11 EDCA and DCF: A Testbed Approach

    There has been considerable research into the performance of the enhanced IEEE 802.11e standard in recent years. Majority of the performance analysis has been based on simulations and analytical models, with little testing done in a real-world environment. The authors investigate the behaviors of the Enhanced Distributed Channel Access (EDCA)...

    Experimental Investigation of IEEE 802.11e EDCA

    The authors investigate the performance of IEEE802.11e Enhanced Distributed Channel Access (EDCA) using real world hardware in a realistic indoor working environment. TCP streams of different priorities representing traffic types, such as FTP are tested over a wireless network test-bed. Quality of Service (QoS) metrics such as throughput and delay...

    Impact of Error Characteristics of an Indoor 802.11g WLAN on TCP Retransmissions

    In this paper, the authors present the results of extensive measurements made over an experimental wired-to-wireless testbed, which consisted of a TCP protocol combined with a real-world indoor IEEE 802.11g WLAN. They investigated the effects of signal attenuation due to client distance from the AP on the 802.11 Frame Error...

    Investigation of H.264 Video Streaming Over an IEEE 802.11e EDCA Wireless Testbed

    Although a number of investigations have been conducted using IEEE 802.11e enabled networks to stream class differentiated video, very few reports are available based on a real testbed. In the paper, the authors set up a wireless testbed for H.264 video streaming through assigning the partitioned video packets onto the...

    It's The Evidence, Stupid: Doing And Legitimizing Policy-Funded Research

    This paper explores the policy and methodological implications of research commissioned by the Enterprise Directorate of BERR, which sought to explain the impact of government regulation on small business performance. The authors suggest that the Directorate's role in "Promoting and developing evidence based policy" had both an enabling and constraining...

    Effect of Fading Correlation on the Performance of Cooperative Systems With Multi Relay Nodes

    Research on cooperative communication has revealed potential benefits from employing this technique in wireless networks. However, most of the work in this field pays little attention to the impact of correlation on the performance achieved. In this paper, the effect of fading correlation on the mutual information of a cooperative...

    An Improved Urban Macrocellular Model for MIMO Wireless Systems

    The authors present an improved model for outdoor MIMO wireless channels and its spatial fading correlation and capacity performances. The proposed model is more representative than the traditional independently and identically distributed (i.i.d) model by considering the remote scatterers on top of the "One-ring" model. They consider both local and...

    Sparsely-Spread CDMA - A Statistical Mechanics Based Analysis

    Sparse Code Division Multiple Access (CDMA), a variation on the standard CDMA method in which the spreading (signature) matrix contains only a relatively small number of non-zero elements, is presented and analysed using methods of statistical physics. The analysis provides results on the performance of maximum likelihood decoding for sparse...
